获取数组中数组的名称？

Question

How can I get the string name 'bar' instead of its contents ? Never found a solution for this one? I want console.log("?") to say 'bar'

let foo = [1,2,3], bar = [11,22,33], hello = [111,222,333]
    let arr = [foo, bar, hello]
    console.log(arr[1])
    // returns 11, 22, 33  ** I know this
    // I want it to return "bar" ?

Answer 1

As far as I know, you cannot do that. You might need to use an object for that

Answer 2

As said above, you can't do this the way it is.

You could however, attach a name property to each base array.

For example:

 const arr1 = [1,2,3], arr2 = [2,3,4]; arr1.name = "arr1"; arr2.name = "arr2"; const arrBoth = [arr1, arr2]; console.log(arrBoth[0].name);
