JavaScript (JS) is one of the implementations of a standardized specification, called ECMAScript. The version of the specification you most know is probably version 5: that's the one used for many years.

For some time, a new version of this specification has been under construction: ECMAScript 6, ES6, or ECMAScript 2015. I will now call it systematically ES6 because it's his little most popular name. It adds a ton of features to JavaScript, like classes, constants, arrow functions, generators ... There are so many things that we can not do everything cover, except to devote entirely to this book. But Angular was designed to benefit from this new version of JavaScript. Even if you can still use your good old JavaScript, you'll have full of advantages to use ES6.

With ECMAScript 6, several new features have been added to the language such as new reserved words to define variables and constants, symbols, interpolation of variables in strings, restructuring, abbreviated form to declare functions, new, simpler syntax for defining classes, objects of type Map and Set , Promises as an alternative to callbacks , the Iterator protocol and generators, in addition to some other things that if like me you had not spent time learning better JavaScript are still new.

Until now as a web developer for almost all my working life, I had not spent time knowing in more detail the JavaScript programming language used in web browsers. Much of what I needed was enough with libraries like jQuery or underscore . Now some web pages have an important weight on the client-side and in view of this need the JavaScript language is evolving and incorporating new features such as those defined in its ECMAScript specifications .

To learn in much more detail how little I knew about JavaScript I read the book Learning JavaScript that covers the news of ECMAScript 2015 also known as ECMAScript 6 (ES6). After reading it, I will say that it is a book that I liked a lot and I think it is suitable both for someone who may be learning to program and for someone who already knows other programming languages ‚Äč‚Äčexplaining the concepts without complications.

We will leave many aspects aside, and we will not be exhaustive on what we will see. If you already know ES6, you can skip this chapter directly. Otherwise, you'll learn stuff rather incredible ones that will serve you in the future even if you do not finally use Angular!
