Learn the fundamentals of JavaScript to make the React journey smooth.

Android Development with Ionic and React

Most of React comes down to JavaScript ES6 and its features and syntax. The fundamentals also include ternary operators, shorthand versions in the language, objects such as “this”, and JavaScript’s built-in functions (map, reduce, filter). It also includes general concepts such as composability, reusability, immutability, or higher-order functions. While we don’t necessarily need to master all these before starting with React, they will come up while practicing it, and learning these concepts will benefit us. 
This module will give us comprehensive JavaScript skills that will make our React journey smooth and straightforward.
