API
In this directory you'll find all the public interfaces to using Babel for both node and the browser.
Node
There are two ways people use Babel within Node, they either are manipulating
strings of code with babel.transform or babel.parse, they also might be
running their code through Babel before execution via register or polyfill.
Browser
Usage of Babel in the browser is extremely uncommon and in most cases
considered A Bad Idea™. However it works by loading <script>'s with XHR,
transforming them and then executing them. These <script>'s need to have a
type of "text/ecmascript-6", "text/babel", or "module" ("text/6to5" exists as
well for legacy reasons).
