JavaScript From The Start
Finding Matches in Arrays
Hide/Show description
In this tutorial I talk about different approaches to finding matching elements inside of arrays and how you can make your code more efficient.
Array.prototype.indexOf() //returns index number
Array.prototype.contains() //returns boolean
Array.prototype.filter() //returns array
Array.prototype.some() //returns boolean
