Transpilation

Transpilation is defined as source-to-source compilation. Tools have been written to do this and they are called transpilers. Transpilers take the source code and convert it into another language. Transpilers are important for two reasons. First, not every browser supports every new syntax in ES6, and second, many developers use programming languages based off of JavaScript, such as CoffeeScript or TypeScript.

Note

The ES6 compatibility table can be found at https://kangax.github.io/compat-table/es6/.

Looking at the ES6 browser compatibility table clearly shows us that there are some holes in support. A transpiler allows us to write our code in ES6 and translate it into vanilla ES5, which works in every browser. It is critical to ensure that our code works on as many web platforms as possible. Transpilers can be an invaluable tool for ensuring compatibility.

Transpilers also allow us to develop web or server side applications in other programming languages...
