## compose.js
// Compose functions from right to left
const compose = (...fns) => x => fns.reduceRight((y, f) => f(y), x);

// Example
const lowercase = str => str.toLowerCase();
const capitalize = str => `${str.charAt(0).toUpperCase()}${str.slice(1)}`;
const reverse = str => str.split('').reverse().join('');

const fn = compose(reverse, capitalize, lowercase);

## curry.js

const curry = (fn, ...args) => {
  return fn.length <= args.length ? fn(...args) : curry.bind(null, fn, ...args);
}

// Example
const sum = (a, b, c) => a + b + c;

curry(sum)(3)(4)(5);    // 12
curry(sum)(3, 4, 5);    // 12

## strings-utils.js
const slugify = string => string.toLowerCase().replace(/\s+/g, '-').replace(/[^\w-]+/g, '');

const kebabToCamel = str => str.replace(/-./g, m => m.toUpperCase()[1]);

const camelToKebab = str => str.replace(/([a-z0-9])([A-Z])/g, '$1-$2').toLowerCase();

const toPascalCase = str => (str.match(/[a-zA-Z0-9]+/g) || [])
  .map(w => `${w.charAt(0).toUpperCase()}${w.slice(1)}`).join('');

// Examples

## random.js
// generate random string
const generateString =
      (length, chars) => Array(length)
		.fill('')
		.map((v) => chars[Math.floor(Math.random() * chars.length)])
		.join('');

// Example
generateString(10, '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ');

## bootstrap.js
beforeEach(function() {
    env = sinon.sandbox.create();
    //stub all requests to server
    $ajax = env.stub($, 'ajax');
});

afterEach(function() {
    env.restore();
});
