JavaScript Functions

up:: JavaScript Functions are just JS Objects. In that way, they are JS Non-primitives.

Functions

`function add(first,second)

• every code we want to run more than once

• return myVar: Returns the value of myVar

• => (parameters → return)

• Browser API

• JavaScript Arrow Functions

Rest operator

function sortArg(...args) {
	return args.sort();
}

Closures

When a function is defined, JavaScript locks in all variables used in it.
