How can I get an element of one object where the object has the element id="..."

Question

I receive answer from a form. I receive an array with objects where each object correspond to the answer of one question:

I want to access the answer.

First I was thinking to ask to use answers[i].t (for example), but the problem is that the number of the question depends of the answers submitted so I can't use index of the array. So I had the idea to access to the answer by using the id of the question.

For example: object.t where object.q === "64c3980b7e457155fed418db".

How can I do that in JavaScript?

The equivalent of a 'where' clause when searching through an array of objects would be either [`filter()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter) or [`find()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find) — Rory McCrossan, Aug 01 '23 at 10:07

const getId = answers?.findIndex(object.q === "64c3980b7e457155fed418db");

Do not add code only answer. Explain what it do – Jens Aug 01 '23 at 10:12
If you're going to use the `findIndex` route, you should probably also show the step where you are actually getting the object from the array. – General Grievance Aug 01 '23 at 13:56

Use the find method:

answers.find(item => item.q  === "64c3980b7e457155fed418db");
