From Powerwash to React Native

I seem to end up powerwashing my Chromebook all of the time, to the extent that the process of regaining my full development environment in under an hour has become as minimal as I intend to make it.

Since I feel that I've gone as far as I can, I figured documenting the steps involved might be of some value to you. I've tried this on a number of different Chromebooks, so you shouldn't hit any major stumbling blocks*. However, if you do, feel free to tweet me @cawfree.

So, here's the no deep sh*t guide on how to make your Chromebook React Native ready.

From scratch.

export const toCamelCase = (e) => {
  return e.replace(/_([a-z])/g, (g) =>  g[1].toUpperCase());
};

export const toSnakeCase = (e) => {
  return e.match(/([A-Z])/g).reduce(
    (str, c) => str.replace(new RegExp(c), '_' + c.toLowerCase()),
    e
  )
  .substring((e.slice(0, 1).match(/([A-Z])/g)) ? 1 : 0);
