Javascript search for an object key in a set

Question

Is it possible to use the javascript \"Set\" object to find an element with a certain key? Something like that:

let myObjects = [{\"name\":\"a\", \"value\":0         


        

Answer 1

Actually a response to Efficiently find an item in a Set but they've closed it as a duplicate #ftw

An alternative approach:

class ArraySet extends Set {

    find(predicate) {
        for(var x of this)
            if (predicate(x)) return x;
        return undefined;
    },

    ... other Array.prototype stuff here

}

const things = new ArraySet([
    { x: 1 },
    { y: 2 }
]);

const found = things.find(item => item.y === 2);
