How to get indexOf that matches this string from an array in javascript

What I am trying to do is: Get foobar from an array if it contains foo

I usually just use indexOf, but this time I don't have the exact string and I don't know to make use of the includes function

Here is my code sample:

  var array = "Hello world, welcome to the universe.";
  var str = array.split(" ");
  var foobar = str.indexOf(this.includes("uni"));

This should get you the index if that is what you are looking for.

var array = "Hello world, welcome to the universe.";
var str = array.split(" ");
var foobar = str.indexOf(str.find(word => word.includes("uni")));

console.log(foobar);

You can use Array.find() instead, which returns the first item for which the given predicate returns true. In the event that no item in the array satisfies the predicate, the result of .find() will be null.

var array = "Hello world, welcome to the universe.";
var str = array.split(" ");
var foobar = str.find(word => word.includes("uni")); //Find first word that includes "uni"

console.log(foobar);
