concat() Array Method in JavaScript

What do you do when you have two arrays but only need one? You concat them:

var words = [“cockapoo”, “beefalo”]

var moreWords = [“pegacorn”, “schnoodle”]

var allWeirdWords = words.concat(moreWords)

// [ “cockapoo”, “beefalo”, “pegacorn”, “schnoodle” ]

Syntax

firstArray.concat(secondArray);

Remember! The array before the concat() method will be placed before the array inside the parenthesis once they are combined.
