Does it have any problem to define same variable name on the multi modules in javascript

Question

I'm trying sublet big single source code to small modules. I want to use same variable name on each jsfile. But them are required on mainjs file.

Does it makes any problem?

main.js

require('./module1');
require('./module2');

module1

let obj = new Something();

module2

let obj = new Something();

No, there's no problem. That's the whole point of having modules. — Patrick Roberts, Jul 18 '19 at 18:11
In your `main.js` you need to assign them to two unique variables. — Rastalamm, Jul 18 '19 at 18:12
@PatrickRoberts So Your mean is it has no problem when I use this variables on different modules? — JunheePark, Jul 18 '19 at 18:16

Each module is a separate entity and you can use same variables in different modules. But not same variables in a single module. By means of a separate entity is that stack of variables are maintained separately for each module when its complied.

If we import all these modules that share the same variable name into for example index.js, how would that play out? – yamanidev Sep 29 '21 at 16:56
