Except on almost any serious project you should be using a transpiler anyways.

Agreed, but I find it helpful to understand the transpiled code. The "clean" ES5 output was a large reason for using TypeScript https://blog.asana.com/2014/11/asana-switching-typescript/

I agree to an extent, but any modern transpired should also emit source maps which should shield most people from needing to look st or understand the "low level" generated code.

It converts your ES6 code into Javascript that can run on all browsers. It's how you can get advanced Javascript features before the browsers fully implement them. Look up Babel.

Converts modern JavaScript to ES5

It is a portmanteau of translater + compiler
