Q349: How do you combine two or more arrays - JavaScript Internals (521 Qs)

The concat() method is used to join two or more arrays by returning a new array containing all the elements. The syntax would be as below,

javascript

  array1.concat(array2, array3, ..., arrayX)

Let's take an example of array's concatenation with veggies and fruits arrays,

javascript

  var veggies = ["Tomato", "Carrot", "Cabbage"];
  var fruits = ["Apple", "Orange", "Pears"];
  var veggiesAndFruits = veggies.concat(fruits);
  console.log(veggiesAndFruits); // Tomato, Carrot, Cabbage, Apple, Orange, Pears
