Destructuring Assignments

Destructuring assignments can be used with any depth of array and object nesting to help pull out deeply nested properties:

someObject = { a: 'value for a', b: 'value for b' }
{ a, b } = someObject
console.log "a is '#{a}', b is '#{b}'"

This is especially useful in Node applications when requiring modules:

{join, resolve} = require('path')

join('/Users', 'Alex')
