JavaScript Function Crash Course | Declaration, Expression & Arrow Functions, Hoisting...

Functions is to Javascript what a lightsaber is to a Jedi. They are one. Today we will look at the basics of functions in Javascript.

Today we are going to learn about Javascript functions. I’m going to share some small but very important little details and tips that took me a long time to figure out but are very important and confused me when I started to code.

Function declarations and function expressions
Camel Case
What happens if we name a function the same name
Parameters and Argument
Function two parameters

Function expressions
Anonymous function
Hoisting we can’t call a function expression before the function
Arrow Function

When to use function expressions and function declarations is beyond the scope of this video but short. If you need a function that is available globally from everywhere you use function declarations otherwise function expressions. But this is very generalized.
