In this course, we'll be using Babbel as our transpiler for our code, since it is very popular in
Transpiling, the ES6 code.
So basically what Babel JS does, it takes in the ES6 code and it outputs the ES6 code as the Es5 code.
It was first created by Sebastian McKenzie, who now works at Facebook.
And you would also notice that Babel JS is one of the primary tools used in React.
