//Not changing the array (non destructive):
let array = ["zero", "one", "two"];
let newElement = array[1];
console.log(newElement); //"zero"

//Removing the extracted item from the array (destructive):
let array = ["zero", "one", "two"];
let spliced = array.splice(0,1); //remove 1 element/s starting at position 0
console.log(array); //["one", "two"]
console.log(spliced); //["zero"]
