Javascript list contains a string

Does anyone know of a way to check if a list contains a string without using indexOf? In my array some strings can contains parts of others, so indexOf will produce false positives.

As an example, how would I determine if "component" is in the array below?

["component.part", "random-component", "prefix-component-name", "component"]

Update:

It seems like my use of false positive was misleading. I meant that it would say that component was in there 4 times, when I want to match the string by itself.

ie. It should return false when checking for the presence of "component" in the below array.

["component.part", "random-component", "prefix-component-name"]

Answer

Use the Array.find API.

Example:

"use strict";

let items = ["component.part", "random-component", "prefix-component-name", "component"];

let found = items.find(item => { return item === "component.part" } );


if (found) {
    console.log("Item exists.");
}

For more usage example.
