] | You can use `reduce` and `includes` as others have already shown. This will make the code a bit cleaner, but not change the overall runtime complexity. To improve runtime complexity you may need to use a different data structure.

70,912,921 | I am trying to improve the time complexity and quality of the code snippet below.
I am iterating through one array to check if the element this array exists in the object, should this be true it should return the name matching the element id in the object.
how can I do this without having a nested loop?

] | The simplest improvement would probably be converting `genres` to a Set <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set>
and use the `has` method to check if each id in the data is a member of the set of chosen genres.
You can also convert the data to a map with the ids as the key... | The current time complexity is O(MN) where M is the length of `data.genres` and N is the length of `genres`.
Time complexity in JavaScript depends on which engine you use, but in most cases you can use a `Map` to reduce this time complexity to O(max{N,M}):

] | You wanted this in one loop, so here it is:

let result = [];
data.genres.forEach(function (e) {
if (genres.includes(e.id)) result.push(e.name);
});
console.log(result);
