How to Code

• Flat over nested
• Simple over complex
• Referential transparency over stateful
• Explicit over implicit/magic
• A smaller/shorter program is a better program
• Maintainability over being terse/parlour tricks
• Concrete over abstract
• Modular over monolithic; modules over frameworks/libraries

'use strict';

var str = 'foobarbaz';
var regexp = /bar/;
console.log(str.match(regexp)); //=> [ 'bar', index: 3, input: 'foobarbaz' ]
console.log(regexp.exec(str));  //=> [ 'bar', index: 3, input: 'foobarbaz' ]
console.log(regexp.test(str));  //=> true
