[...Array()] is equal to new Array() in js code example

Example 1: js array

var colors = [ "red", "orange", "yellow", "green", "blue" ]; //Array

console.log(colors); //Should give the whole array
console.log(colors[0]); //should say "red"
console.log(colors[1]); //should say "orange"
console.log(colors[4]); //should say "blue"

colors[4] = "dark blue" //changes "blue" value to "dark blue"
console.log(colors[4]); //should say "dark blue"
//I hope this helped :)

Example 2: array javascript

var familly = []; //no familly :(
var familly = new Array() // uncommon
var familly = [Talel, Wafa, Eline, True, 4];
console.log(familly[0]) //Talel
familly[0] + "<3" + familly[1] //Talel <3 Wafa
familly[3] = "Amir"; //New coming member in the family
