anonymous functions javascript

/*
Anonymous function = a function that doesn't need a name, you only need it for the 
purpose of a single callback
*/

// e.g.

const arr = [1,2,3,4]
arr.map(function square(num){
	return num * 2
})

// the 'square' function is only used within .map here. So it can be treated as an 
// anonymous function. Short hand for an anonymous function can look like this:

arr.map(function(num){
	return num * 2
})

// Or using arrow notation it can look like this:

arr.map((num) => {
	return num * 2
})
