ARROW FUNCTIONS vs FUNCTION EXPRESSIONS vs FUNCTION DECLARATIONS (BYTE CODE)| Advanced JavaScript

Video Description

This video is a full deep dive into Function Declarations, Function Expressions and Arrow Functions work both at a usage level and underneath the hood at a byte code level. As well as looking at the differences in usage (such as hositing), this video also looks at named functions, inferred name functions and anonymous functions. You will have a deep understanding of how functions work underneath the hood and how they differ in the generated byte code. There are of course some considersations in the usage of arrow functions and naming which include naming collisions and debugging experience that should be considered also. We look at some of the gotchas in using arrow functions such as binding, and how usage of the this keyword changes (especially impactful for objects). You will gain a deep understanding of these ES6/ES2015+ features.
