Angular is built with AtScript. AtScript is an extension of ES6 (ECMAScript 6), the new specification of the JavaScript language. This quickstart features AtScript, but you can write Angular in ES5 or ES6 as well.
ES6
AtScript compiles to ES6, which is not widely supported in all browsers today. The es6-shim.js file allows you to use ES6 or AtScript in the browser.
es6-shim
The quickstart repository includes es6-shim.js. The es6-shim.js file includes dependencies (such as Traceur) needed to compile ES6 in the browser. Traceur is an ES6 compiler that transpiles ES6 to ES5 code.
