Typescript for ES6 developers

# Default import from commonJS module

## ES6

import chai, { expect } from 'chai';
import chaiAsPromised from 'chai-as-promised';
chai.use(chaiAsPromised);

## Typescript

import chai = require('chai');
import chaiAsPromised = require('chai-as-promised');
let expect = chai.expect;
chai.use(chaiAsPromised);

## TypesScript (alternative)
import * as chai from 'chai'
import { expect } from 'chai'
import * as chaiAsPromised from 'chai-as-promised'
chai.use(chaiAsPromised);
