50 Days React Bootcamp: Build 50 Real World React Projects

React uses declarative instead of imperative syntax. It’s a simpler way of developing apps, and you can learn why here.

Basically, React is faster to develop with because you don’t need to tell the app how to represent the state — you just need to say what you’d like to happen. It’s quick, it’s easy, and there’s less room for human error.

You may have heard of the phrase “Write once, run anywhere” before. React Native brings that kind of philosophy to React with “Learn once, write anywhere”.

Once you understand the basic architecture and thinking behind React, you’ll be able to develop fully functioning apps for both Android and iOS. You won’t have to learn two different ways to represent your app. So after you learn React, you can bring your new product to users not just as quickly as possible, but as widely as possible.

React JS is an open–source, component–based Javascript library, which is used to build UI specifically for single–page applications. It’s one of the most popular Javascript libraries used to build apps front–end right now. Facebook developers created ReactJS in 2011 and used first in the Facebook app, and until today it has a huge community supporting it and lots of resources to learn it.
