// Let's declare an array of DC heros
let dcHeros = [

// Now let's declare another array of Marvel heros and merge both the arrays
// The spread operator will extract the values of the previous array (dcHeros)
// to the current array.
let marvelAndDcHeros = [
	'Captain America', 'Ironman', 'Hulk', ...dcHeros

// Loop through the new array
for (let hero of marvelAndDcHeros) {

// Above will output:
// Captain America
// Ironman
// Hulk
// Superman
// Batman
// Wonder Woman
