JS | How to make one variable a link to another

Instead of just assigning the value of var b to var a via a = b;,

I‘d like to make a ‚link‘ to b, so that when a is changed, actually b is changed and when a is used, actually b is used, so to say. Is that possible?

My code has immensely long arrays, and setters/getters aren’t always muuuch more readable. And even besides my current use case, it would be great to know whether something like that exists (in javaScript).

Thanks in advance.

What's wrong with using objects?

const a = {
  current: 5,
}

const b = a

b.current = 10

console.log(a, b)
