language.toString() 
// join : Biến Array thành 1 chuỗi bằng cách đưa ra điểm chung
language.join()
// pop : Xoá element cuối array và trả về phần tử đã xóa
language.pop()
// push : Thêm 1 hoặc nhiều element cuối array và trả về độ dài mới của array
language.push('NodeJS')
// shift : Xóa đi phần tử ở đầu array
language.shift()
// Thêm 1 hoặc nhiều element đầu array và trả về độ dài mới của array
language.unshift('NodeJS')

// splice : Hàm dùng để xóa các phần tử trong array, 
// Và thêm 1 hoặc nhiều element
// Tham số 1 vị trí bắt đầu đặt trỏ chuột xóa
// Tham số thứ 2 xóa bao nhiêu element (if 0 thì ko xóa)
// Tham số thứ 3
language.splice(1, 0, 'JAVA')

// concat : Dùng để nói 2 mảng với nhau
// language.concat(language2)

// slice : Dùng để cắt 1 hoặc nhiều element của array
// Dùng để copy array, có 2 tham số giống splice

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 :)
