How can I search through an array of objects for a unique id?

I have an array of objects and a unique id. I'd like to search through the array of objects for the object instance that matches the unique id, but I'm not sure how to begin to approach it.

idToSearchfor = 2

arrayToBeSearched = [{content: 'string', id: 1}, {content: 'string', id: 2}, {content: 'string', id: 3}]

That's what Array.prototype.find() is for, assuming you're certain you will never have more than one matching item (find only returns the first matching item):

let idToSearchfor = 2;

const arr = [{content: 'string', id: 1}, {content: 'string', id: 2}, {content: 'string', id: 3}]

console.log(arr.find(x=>x.id===idToSearchfor));

Otherwise (several possible matches), use Array.prototype.filter():

let idToSearchfor = 2;

const arr = [{content: 'string', id: 1}, {content: 'string', id: 2}, {content: 'string', id: 3}]

console.log(arr.filter(x=>x.id===idToSearchfor));
