Even though for most people, these days can feel dull, it’s students and employees that can jump at this opportunity. Web app development and mobile app development are two tech skills that you can master during your free time.

App development is a huge market to tap into. By 2016, around 130 billion apps had been downloaded from the Apple App store worldwide, and approximately 65 billion apps had been downloaded from Google Play. While there are plenty of program languages out there, these 5 are the most popular ones to focus on. Check out these top applications and figure out which one you should learn during this COVID-19 to enhance your skills.

Web and Mobile Development Languages







Angular JS

This programming language is perfect for small web app development. Nowadays, it’s necessary to have excellent skills in this programming language to be a front-end developer. Its demand has rapidly increased due to blockchain technology. Angular JS is primarily meant for designers.

It’s a toolkit for creating the most suitable frame for app development. Each feature can be changed to match your workflow and requirements. Angular JS enables you to put out HTML vocabulary to your application giving you an easy to develop environment. It’s also testable and injectable.

Its data-binding feature allows you to change the view as the model changes and update the model with a change in the view. With Angular JS, you can express the behavior behind DOM elements without updating it. Your code can be maintained and reused easily with these plain JavaScript objects. Reusable components can be formed using directives. It enables your application to be obtainable in all locales.

New features like geolocation, microdata, semantic elements, WebSocket, and canvas are ideal for modern web app development and can easily convert a website into mobile application.

The demand and usage of HTML5 is just increasing at a rapid page. Almost at every development centered requirement, HTML5 can help in bringing a lot of diversity and range to the output.

Summing up

Mobile apps are expected to generate $189 billion in revenue by 2020. In today’s tech-savvy world, knowing a programming language can be extremely useful and set you apart. Web and mobile app development is a valuable skill that can help you get ahead in top tech companies.

Angular JS, Python, Java, Swift, and HTML 5 are the future of app development languages and will be advantageous in the coming years. Due to the coronavirus outbreak, students and IT professionals all over the world have more time than ever. If you’ve been thinking of doing something worthwhile with your time during the lockdown, you know where to start.
