var secondVariations;

this is the array of object name what you are seeing in the image.

I have the above Array of Object. But I can't search an item in this. What is the problem?

It's giving me undefined

let value_of_select = 7;
let variationListTargettedValueOfSelect = secondVariations.find(obj => {
       return obj.id === value_of_select;
});

I also used filter but same result! What my mistake?

Code Structure:

var secondVariations;
$.ajax({
   -----
   success:function(response){
      secondVariations = response;
});

// I have a select-option in success {} block. After firing this 

$(document).on('change', '.select-class' , function(){
let value_of_select = 7;
let variationListTargettedValueOfSelect = secondVariations.find(obj => {
       return obj.id === value_of_select;
});
});

`console.log(variationListTargettedValueOfSelect )` what prints? – Alberto Sinigaglia Sep 10 '20 at 16:14
Are you assigning the variable in an async function? – Barmar Sep 10 '20 at 16:14
Nothing wrong with your code. Can you share the entire function where you are using this. – Anup Sep 10 '20 at 16:18
Include a reproducable example. – junvar Sep 10 '20 at 16:18
you should post the snippet code completely to see what is going on – Bob White Sep 10 '20 at 16:18
@Berto99, giving me `variationListTargettedValueOfSelect ` undefined – Aspile Inc Sep 10 '20 at 16:21
Please provide a [mcve]. – Unmitigated Sep 10 '20 at 16:21
I have added my code Structure. Actually it's very big code to share. – Aspile Inc Sep 10 '20 at 16:25
@Barmar you got it ahaha – Alberto Sinigaglia Sep 10 '20 at 16:27

@AspileInc Barmar will probably explain it on a answer, but to sum up, `$.ajax` is async, and so `filter` might me executed before the `success` callback is fired – Alberto Sinigaglia Sep 10 '20 at 16:28
You need to put the filter code in the `success` function. – Barmar Sep 10 '20 at 16:30
Oh. Then I am going to Brute Force method. `for` loop. It's a better solution now. But I don't know about the complexity!! :-D – Aspile Inc Sep 10 '20 at 16:34
