array JS

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 :)

Metode Array JavaScript

let dailyActivities = ['sleep', 'work', 'exercise']
let newRoutine = ['eat'];

// sorting elements in the alphabetical order
dailyActivities.sort();
console.log(dailyActivities); // ['exercise', 'sleep', 'work']

//finding the index position of string
const position = dailyActivities.indexOf('work');
console.log(position); // 2

// slicing the array elements
const newDailyActivities = dailyActivities.slice(1);
console.log(newDailyActivities); // [ 'sleep', 'work']

// concatenating two arrays
const routine = dailyActivities.concat(newRoutine);
console.log(routine); // ["exercise", "sleep", "work", "eat"]
