Angular2 + JSPM cheat sheet

First time setup

install jspm beta: npm install -g jspm@beta
set up your project: jspm init
install dependencies: jspm install angular2 reflect-metadata zone.js es6-shim

This will create a jspm_packages folder, and a config.js file.

Open the config.js file - this file manages options for the System.js loader - tweak it as appropriate

Angular2 Migration Guide

This guide will show you how to upgrade from Angular beta-* to rc-* JSPM Guide Starting at RC0, all the modules are broken out seperate. See: https://github.com/angular/angular/blob/master/CHANGELOG.md#200-rc1-2016-05-03

First off, to prevent JSPM from brining in a crazy amount of Angular2's package.json depedencies, you need to override the default config. For more information on this see: angular/angular#7412

Parens And Performance

Years ago, some smart folks that worked on JS engines realized that not all JS that's loaded into a page/app initially is needed right away. They implemented JIT to optimize this situation.

JIT means Just-In-Time, which means essentially that the engine can defer processing (parsing, compiling) certain parts of a JS program until a later time, for example when the function in question is actually needed. This deferral means the engine is freer to spend the important cycles right now on the code that's going to run right now. This is a really good thing for JS performance.

Some time later, some JS engine devs realized that they needed to get some hints from the code as to which functions would run right away, and which ones wouldn't. In technical speak, these hints are called heuristics.

So they realized that one very common pattern for knowing that a function was going to run right away is if the first character before the function keyword was a (, because that usually m
