Destructuring Arrays

Extract values into variables

let colors = ["red", "green", "blue"];

// Old way
let firstColor = colors[0];
let secondColor = colors[1];

// With destructuring
let [first, second, third] = colors;
console.log(first);  // "red"
console.log(second); // "green"

// Skip elements
let [primary, , tertiary] = colors;
console.log(primary);  // "red"
console.log(tertiary); // "blue"
