JavaScript’s this keyword is a source of confusion for new and experienced developers alike. It can be frustrating if, for some reason, this doesn’t point to the context that was intended.

This course will help you understand JavaScript’s this mechanism in-depth. Marius will take us through all of the ways this will change its values, from why many libraries use "use strict" to how arrow functions take its outer execution context’s this .

Over 8 lessons, you’ll learn:

value of that function invocation how to call a function with a specific this value

value how to create functions that always remain tied to a specific this context

how this is treated within arrow functions and classes
