To make an application and website interactive, programmers and developers from all over the world use JavaScript. With time, it has been gaining more popularity as there is no other language that can substitute for JavaScript. No website is complete without JavaScript coding. And that’s the reason it is frequently used. Even beginners are trying to be familiar with the language to make sure to step in the shoe of the pro programmers. Programming has become simpler with JavaScript frameworks. React Native is one of the popular JavaScript frameworks. It is ideal for creating native mobile applications.
