Assume I have the following namespaces

window.myNameSpace.1.someName

window.myNameSpace.2.someName

Also, assume that I have a runtime variable x, where x could be either 1 or 2

let x = 1; // x is 1 in this case, but could be 2

Now, based on the value of x, I could do this

switch (x) {
    
    case 1:
        let someName = window.myNameSpace.1.someName;
        break;

    case 2
        let someName = window.myNameSpace.2.someName;
        break;
}

This works and is great.

However, can I do something like this to make code more concise? (please note this is a pseudo code and not correct, this is the idea)

let someName = window.myNameSpace.<x>.someName; // replace <x> with the variable

And thus making the code much shorter and more efficient, especially if I have a lot of values for x and a number of namespaces.

Thanks.

Are you talking about accessing an object property dynamically? `let myVariable = 'myKey'; let someName = window.myNameSpace[myVariable].someName;` – Alexander Staroselsky Oct 09 '20 at 16:14
@AlexanderStaroselsky - Thanks. So the `myVariable` has to be a string? And does it work in namespaces? I will try this. Thanks again. – Greeso Oct 09 '20 at 16:20
Did you try it with both a number or a string, what happens? – Alexander Staroselsky Oct 09 '20 at 16:21
@AlexanderStaroselsky - About to try it now. – Greeso Oct 09 '20 at 16:22
@AlexanderStaroselsky - Number does not work, however your suggestion in the comment above works as a string. Maybe you like to add your comment as an answer? For future reference. Thanks a lot. – Greeso Oct 09 '20 at 17:19
For whoever closed the question, this is not the same as the suggested duplicate. Please re-oopen – Greeso Oct 09 '20 at 17:21
It does work with numbers: https://jsfiddle.net/kygtac83/ – Alexander Staroselsky Oct 09 '20 at 17:22
@AlexanderStaroselsky - You are right. I did something else. Apologies. Thanks again. – Greeso Oct 09 '20 at 17:23
