javascript - Check if an array of strings contains a substring

I have an array like this:

array = ["123", "456", "#123"]

I want to find the element which contains the substring "#". I tried array.includes("#") and array.indexOf("#") but it didn't work.

How can I check if any of the strings in this array contain the substring "#"?

See Question&Answers more detail:os

Because includes will compare '#' with each array element.

Let's try with some or find if you want to find if you want to get exactly element

var array = ["123", "456", "#123"];

var el = array.find(a =>a.includes("#"));

console.log(el)
