Convert a dash/dot/underscore/space separated string to camelCase:
foo-bar→fooBar
$ npm install --save camelcase
const camelCase = require('camelcase');
camelCase('foo-bar');
//=> 'fooBar'
camelCase('foo_bar');
//=> 'fooBar'
camelCase('Foo-Bar');
//=> 'fooBar'
camelCase('--foo.bar');
//=> 'fooBar'
camelCase('__foo__bar__');
//=> 'fooBar'
camelCase('foo bar');
//=> 'fooBar'
console.log(process.argv[3]);
//=> '--foo-bar'
camelCase(process.argv[3]);
//=> 'fooBar'
camelCase('foo', 'bar');
//=> 'fooBar'
camelCase('__foo__', '--bar');
//=> 'fooBar'Convert a camelized string into a lowercased one with a custom separator
Example:unicornRainbow→unicorn_rainbow
$ npm install --save decamelize
const decamelize = require('decamelize');
decamelize('unicornRainbow');
//=> 'unicorn_rainbow'
decamelize('unicornRainbow', '-');
//=> 'unicorn-rainbow'
Async is a utility module which provides straight-forward, powerful functions for working with asynchronous JavaScript. Although originally designed for use with Node.js and installable via npm install --save async, it can also be used directly in the browser.

Lodash makes JavaScript easier by taking the hassle out of working with arrays,
numbers, objects, strings, etc. Lodash’s modular methods are great for:
- Iterating arrays, objects, & strings
- Manipulating & testing values
- Creating composite functions
Underscore.js is a utility-belt library for JavaScript that provides support for the usual functional suspects (each, map, reduce, filter...) without extending any core JavaScript objects.
Terminal string styling done right
https://github.com/chalk/chalk.git
colors.js used to be the most popular string styling module, but it has serious deficiencies like extending String.prototype which causes all kinds of problems. Although there are other ones, they either do too much or not enough.
Chalk is a clean and focused alternative.
$ npm install chalkconst chalk = require('chalk');
console.log(chalk.blue('Hello world!'));
