Array of arrays in javascript

Published on : August 13,2022

Hi dev,

In this article we will learn about Array of arrays in javascript.

Array can store different data types including an array itself. Let us create an array of arrays

const firstNums = [1, 2, 3]
const secondNums = [1, 4, 9]

const arrayOfArray = [
  [1, 2, 3],
  [1, 2, 3],
]
console.log(arrayOfArray[0]) // [1, 2, 3]

const frontEnd = ['HTML', 'CSS', 'JS', 'React', 'Redux']
const backEnd = ['Node', 'Express', 'MongoDB']
const fullStack = [frontEnd, backEnd]
console.log(fullStack) // [["HTML", "CSS", "JS", "React", "Redux"], ["Node", "Express", "MongoDB"]]
console.log(fullStack.length) // 2
console.log(fullStack[0]) // ["HTML", "CSS", "JS", "React", "Redux"]
console.log(fullStack[1]) // ["Node", "Express", "MongoDB"]

Hope it can help you…
