JavaScript: How to find the index of a value in an array in JS?

If you have an array of values, and you want to know what index a certain value has, you can use this:

  1. let fruits = ["apple","banana","orange","grapes"];
  2. console.log(fruits.indexOf("orange")); //returns 2, as it is the 3rd item in array but array index starts at 0
