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

If you want your solution to be performant, use Map instead of Set. If your Set is not that big you can go with T.J. Crowder solution and convert Set to Array then filter and vice versa.

let myObjects = [['a',{"name":"a", "value":0}], ['b',{"name":"b", "value":1}],['c',{"name":"c", "value":2}]];
let myMap = new Map(myObjects);
console.log(myMap.has('a'));
