beautify-with-words - Beautifies javascript and replaces variable names with unique "long-ish words"

•    Javascript

beautify-with-words beautifies javascript and replaces variable names with unique "long-ish words". It uses UglifyJS2's beautifier, but uses a phonetic word generator to rename variables. This makes it easier less-hard to read unminified code and do things like search-and-replace. beautify-with-words takes one file at a time – or, if no input file is specified, then input is read from STDIN.

prettier-eslint - Code :arrow_right: prettier :arrow_right: eslint --fix :arrow_right: Formatted Code :sparkles:

•    Javascript

The fix feature of eslint is pretty great and can auto-format/fix much of your code according to your ESLint config. prettier is a more powerful automatic formatter. One of the nice things about prettier is how opinionated it is. Unfortunately it's not opinionated enough and/or some opinions differ from my own. So after prettier formats the code, I start getting linting errors. This formats your code via prettier, and then passes the result of that to eslint --fix. This way you can get the benefits of prettier's superior formatting capabilities, but also benefit from the configuration capabilities of eslint.
