How to Find an Object Key Value Inside an Array

Hi, does anyone know how to find an object key value inside an array? For instance, if I have an array of objects called records.

var records = [{

id: 12345

type: transaction


If I want to check this array to see if there’s an object that contains the ID “12345”, how would I do that? Is there a way without looping through the whole array? I know I can use the array.includes method to find a value inside a regular array. But that doesn’t seem to work because I’m looking for an object key value inside an array.

No, I do not believe there is any more ‘native’ way of doing this.
I would just do something like the following:

function findId(id, records) {
    for (var i = 0; i < records.length; i++) {
      if (records[i].id === id) {
        return true;

Decent article with more generalized function:

Ok, thanks! That’s basically what I ended up doing too. I was just seeing if there was some method that does this that I was unaware of.

If you are using SuiteScript 2.1 and have access to the ES6 array functions in this post, you could use these as well:

Also, if you load the lodash library in, you can use the _.find function. In general, that whole library can be very useful.
