You Don't Know JS: this & Object Prototypes

Chapter 2: `this` All Makes Sense Now!

In Chapter 1, we discarded various misconceptions about this and learned instead that this is a binding made for each function invocation, based entirely on its call-site (how the function is called).

Call-site

To understand this binding, we have to understand the call-site: the location in code where a function is called (not where it's declared). We must inspect the call-site to answer the question: what's this this a reference to?

Appendix C: Lexical-this

Though this title does not address the this mechanism in any detail, there's one ES6 topic which relates this to lexical scope in an important way, which we will quickly examine.

ES6 adds a special syntactic form of function declaration called the "arrow function". It looks like this:

Facebook Privacy Settings for those who still want to use Facebook

Only have five minutes? Read the highlights.

Facebook is an advertising platform that builds profiles about its users through their browsing history and sells them.

Google does the same with your search history and YouTube views. On the other hand, Facebook tracks you because a great number of web sites are littered with Facebook's tiny "Share / Like this" button. A user thinks the button is just there to make sharing easier, but it allows Facebook to keep a record every site the user has been on.
