Understand JavaScript's this Keyword in Depth
Instructor
Marius Schulz
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:
- how JavaScript implicitly sets the
thiscontext, and how we can set it ourselves - that the call-site of a function determines the
thisvalue of that function invocation - how to call a function with a specific
thisvalue - how to create functions that always remain tied to a specific this context
- how
thisis treated within arrow functions and classes
Following the course, this will feel less frustrating, more intuitive, and far more useful in your day-to-day.
