                Using Typescript + Angular 1.x in the Real World
              
          
    Work in progress!

A little while ago I started using Typescript with the Angular 1.5 app I'm working on, to help ease the migration path to Angular 2. Here's how I did it. We'll go example by example through migrating real world code living in a large, mostly non-Typescript codebase.
Let's start with a few of the basic angular building blocks, then we'll go through some of the higher level patterns we derived.

Javascript


## destructuring.js
// === Arrays

var [a, b] = [1, 2];
console.log(a, b);
//=> 1 2


// Use from functions, only select from pattern
var foo = () => [1, 2, 3];

## fork forced sync
git fetch upstream
git reset --hard upstream/master
	// === Arrays

	var [a, b] = [1, 2];
	console.log(a, b);
	//=> 1 2


	// Use from functions, only select from pattern
	var foo = () => [1, 2, 3];
