Angular JS for Startups: Advantages and Disadvantages

Among the most outstanding JavaScript frameworks in the market, today is Angular. Formerly AngularJS, the framework has had a long journey since its inception in 2009 within the walls of Tech Giant, Google. The goal for Angular was to help developers of web applications to make their work easier, following the decline of JQuery as a useful framework. Integrating HTML code with other various application modules, Angular provided a framework that was ideal for the creation of rich websites.

Like any other invention in the tech world, Angular was not with a few setbacks. Being a derivative of JavaScript, Angular began to suffer major setbacks when its parent framework started to get major updates. Furthermore, other frameworks and libraries like Vue and React were rocking the market and making it more and more difficult for Angular to be implemented everywhere. This meant that Angular would require major and consistent improvements if it was to remain on the market. Luckily, engineers at Google were up for the challenge, releasing various versions of Angular which were better and more robust.

Today, Angular 5 is in use, and it provides startups with a framework that is just as promising as any other. Having maintained its initial benefits, Angular 5 comes packed with even more functionality which makes it worthy of startup attention.

Two Way Data Binding

One of the greatest advantages which developers enjoy today is two-way data binding which Angular provides. In two-way data binding, manipulation or changes made in data from each side of a web application (server side and client side) is reflected on the corresponding side. The advantages of data binding for programmers is that testing becomes a much easier job. The identification of processes which interact with and modify data individually gives developers a much clearer picture of the processes and this, in turn, makes the testing of various components a faster process.

Dependency Injection

Angular also receives much of its appraisal and approval from its inbuilt dependency injection features. Dependency refers to a state where an instruction or piece of software relies on data from another piece of software to function. Dependency injection is where one piece of code (such as a class) automatically acquires its dependencies from another piece of code rather than create them itself. Two advantages arise from DI.

First, there is the decoupling of various components of code, allowing even further modularization which makes the code simpler and cleaner. The biggest advantage for DI is that testing of code becomes very simple. If a developer wants to test the performance of a piece of code, all they have to do is manipulate the dependencies of that code and run the appropriate tests. The need to create new dependencies within a class, for instance, is removed.

Simplified Progressive Web Application

PWAs have received much hype in recent months thanks to their ability to combine the beneficial features of web pages with features from native or mobile applications. The latest release of Angular, Angular 5.0, implements the integration of these features in a simpler way while adding other mobile features such as push notifications and the ability to access data while offline.

Custom Directives

Custom directives in Angular allow developers to create their own custom tags within applications as well as manipulation of DOM elements in many ways. It is also possible to style elements with various behaviors, making your web application more responsive and interactive.

Community

An added advantage for startups in using Angular is that there is a vast amount of documentation as well as a strong community support, making the learning and implementation process faster. Developers will spend less time on coding and more on decision-making processes and on building new models for the business to operate.

Angular has many benefits for a startup, but there are hurdles and limitations which may cause difficulties in its implementation and operation overall.

Learning Curve

Angular is a highly detailed and versatile JavaScript framework. Over time, there have been many major iterative improvements made to it which has resulted in a large library and methodology in the completion of tasks. While it may sound like an advantage to have many ways of performing one function, it becomes very confusing and tiresome to decide which is the best for the application in terms of dependencies and the interactions with other components within the application.

Performance

Web applications created using Angular tend to be complex and dynamic. As such, these applications are lacking when it comes to performance. Single page applications built with Angular tend to be large and complex under the hood, making them inconvenient and laggy.

JavaScript Dependent

Being a derivative of JavaScript, Angular fails to function outside of its boundaries. If, say, a user was to disable JavaScript in their browser, they would not be able to see any Angular coded features within a web application, and only the basic page would be visible. This degradable nature of Angular makes it a limited tool in building web applications.

What is most important while considering Angular as a startup company is whether or not it will accomplish the goals you have put down for your web application platform. The number of resources, especially time, is also a significant factor to be considered when making the choice. In general, Angular has more pros than cons to it and may be a good place to start while avoiding progress deadlock in development.

Thanks to ElevenLabs and its state-of-the-art neural network for sound generation, users can now pair the visually stunning 3D locations with sounds that are virtually indistinguishable from reality. By simply describing the desired sound, the neural network works its magic to create a bespoke audio experience. This perfect synergy between Sora’s visual prowess and ElevenLabs’ sonic wizardry opens up a realm of possibilities for creators, allowing them to craft content that not only looks stunning but sounds authentic and immersive. OpenAI’s Sora & ElevenLabs: How Will They Impact Game Development? The emergence of tools like OpenAI’s Sora and ElevenLabs sparks discussions about their potential impact on the industry. Amidst the ongoing buzz about AI revolutionizing various fields, game developers find themselves at the forefront of this technological wave. However, the reality may not be as revolutionary as some might suggest. Concerns Amidst Excitement: Unraveling the Real Impact of AI Tools in Game Development Today’s AI discussions often echo the same sentiments: fears of job displacement and the idea that traditional roles within game development might become obsolete. Yet, for those entrenched in the day-to-day grind of creating games, the introduction of new tools is seen through a more pragmatic lens. For game developers, the process is straightforward – a new tool is introduced, tested, evaluated, and eventually integrated into the standard development pipeline. AI, including platforms like Sora and ElevenLabs, is perceived as just another tool in the toolkit, akin to game engines, version control systems, or video editing software. Navigating the Practical Integration of AI in Game Development The impact on game development, in practical terms, seems to be more about efficiency and expanded possibilities than a complete overhaul of the industry. Developers anticipate that AI will become part of the routine, allowing for more ambitious and intricate game designs. This shift could potentially lead to larger and more complex game projects, offering creators the time and resources to delve into more intricate aspects of game development. However, there’s a sense of weariness among developers regarding the constant discussion and hype surrounding AI. The sentiment is clear – rather than endlessly discussing the potential far-reaching impacts of AI, developers prefer practical engagement: testing, learning, integrating, and sharing insights on how these tools can be effectively utilized in the real world. OpenAI — for all its superlatives — acknowledges the model isn’t perfect. It writes: “[Sora] may struggle with accurately simulating the physics of a complex scene, and may not understand specific instances of cause and effect. For example, a person might take a bite out of a cookie, but afterward, the cookie may not have a bite mark. The model may also confuse spatial details of a prompt, for example, mixing up left and right, and may struggle with precise descriptions of events that take place over time, like following a specific camera trajectory.” So, AI can’t fully create games and its impact might be limited. While it could serve as a useful tool for quickly visualizing ideas and conveying them to a team, the core aspects of game development still require human ingenuity and creativity. In essence, the introduction of AI tools like Sora and ElevenLabs is seen as a natural progression – a means to enhance efficiency and open doors to new creative possibilities. Rather than a radical transformation, game developers anticipate incorporating AI seamlessly into their workflow, ultimately leading to more expansive and captivating gaming experiences.

Virtual Tours of National Parks. Discovering Nature’s Beauty through AR and VR

In this article, we will explore the impact of augmented and virtual reality on national parks, specifically how they are changing our experience of visiting natural landscapes. We focus on free virtual tours that allow us to see the beauty of national parks without leaving home. We will also reveal the main advantages of augmented reality, which enrich the visiting of real parks with the help of digital content with interesting information. In particular, we will share our experience of creating tourist VR excursions using the example of the Carpathian Mountains Virtual Tour and Medieval Fortress Virtual Journey. We will also explore other famous AR/VR use cases, e.g., the State Parks of California, giving us a unique perspective on our national parks’ historical and ecological significance. Discovering Benefits of AR and VR in National Parks Virtual and augmented reality offer such benefits to national parks as Getting informative content on the spot. When visiting parks and other historical places, visitors usually don’t know about this or that type of plant or even in which part of the park they are. With the help of an AR application, a tourist can simply point the screen at a particular plant and get additional information about it. Read also: The Ways AR Redefines Modern Tourism  Speaking about orientation in place, AR navigation will come in handy here, which guides the tourist in the right direction with the help of digital pointers. Read also: From Outdoors to Indoors: AR Navigation as Game-Changer Visiting places that aren’t accessible for you. During the COVID-19 pandemic and home isolation, virtual tours of museums or national parks were one of the popular alternatives to visiting real tourist locations. Even though the pandemic began to gradually fade away, virtual tours continue to be relevant. By visiting free tours on museums or park websites, an Internet user saves money on the ticket, car fuel, and transportation. Especially when a person does not always have an opportunity to get to the place where, perhaps, he would like to go. “The advantage is that you can go somewhere and experience the same feelings without leaving your home. Virtual guides have musical accompaniment, the effect of presence thus allows you to immerse yourself in the environment. This is all about VR. Plus, not all of us can go to Papua New Guinea or somewhere else to look at bamboo, baobabs, etc. Or go on safari. Therefore, these are opportunities to visit somewhere without spending additional funds,” said Oleksandr Ivanov, project manager of Qualium Systems. Drawing attention to ecology, rare plants and animals. As you know, there are more than 35,000 species of endangered plants and animals in the world, 99% of which are endangered due to human activities. With virtual and augmented reality for parks that are the home for these species of animals, it becomes possible to tell about these endangered species to a wider audience. As of July 2023, there are almost 7 billion people in the world who have smartphones, which is more than 86% of the entire population of the planet.  Qualium System’s Virtual Tours of National Parks Qualium Systems has great experience in developing VR excursions. Carpathian Mountains Virtual Tour is an application for Meta Quest, created as part of The World Of Carpathian Rosettes — Activities For Preserving The Cultural Uniqueness Of The Carpathians project by the Euroregion Carpathians — Ukraine association with the financial support of the European Union. The main goal of this program is to preserve the cultural uniqueness of the Ukrainian Carpathians. The main challenge in the development of this virtual tour was to introduce more than 260 photo and video materials into the program while providing the VR headset users with such an experience as if they were visiting a real museum. In this application, a tourist can explore virtual settlements in the Carpathians, both with the effect of presence in these settlements and from a bird’s eye view. There is also the option of a “bicycle trip” available. A tourist can “ride” along the Franko route, which is a path in the forest, famous Ukrainian poet Ivan Franko liked to travel. Also, our developers are working on another virtual tour of the medieval fortress in the Ukrainian town of Tustan. Unlike the previous tour, a VR headset user will not only be able to see the digital environment with exhibits but also interact with them. “With the help of VR, you can not only be there, in that museum, but also take the artifacts, examine, bring them up to your forehead. You could see everything down to every crack,” said Oleksandr Ivanov, project manager of Qualium Systems. Unveiling Diverse Use Cases of AR and VR in National Parks Our company pays attention to virtual tours and giving people the opportunity to see places that are inaccessible to them due to various circumstances. We constantly monitor the latest trends in the modern IT industry, and there are other famous examples that will be mentioned later. Virtual Reality Adventures in California State Parks The California Department of Parks and Recreation has introduced virtual and augmented reality tours for 9 parks located in the state of California. In the Virtual Adventurer mobile app, tourists get a guided tour that tells the story of each of the parks, including Colonel Allensworth State Historic Park, Montana de Oro State Park, Old Town San Diego Historic Park, and others. Moreover, futuristic holograms and 3D reconstructions are also involved. “The app also supports and enhances the department’s Reexamining Our Past Initiative by developing content for parks that tells a more complete, accurate, and inclusive history of people and places,” said California State Parks Director Armando Quintero.  Great Barrier Reef’s Virtual Realms As mentioned above, virtual excursions allow gadget users to get to places they would be unlikely to get to in real life. The same is true for the underwater attractions. Not every tourist wants to spend their time and money not only to reach, for example,…
