Runtime error when using array destructuring? [duplicate]

Question

I am trying to reuse the variables first and second, I am able to update the variable directly, but I can't reuse them for another destructuring statement.

let [first, second] = [1, 2]
[first, second] = [3, 4]

Variables are declared using let, so we can reassign. But, I am getting a runtime error

Also relevant: Do we need semicolon at the end? Do you recommend using semicolons after every statement in JavaScript? Javascript “Uncaught TypeError: object is not a function” associativity question Javascript array destructuring assignment gives strange errors — VLAZ

@VLAZ The problem is that my project uses prettier for formatting. And, I don't get to edit the .prettierrc. So, even if I put a ; there, it would be taken off when the format script runs prior to a commit. — Aman Kumar

As a side note, it's a REALLY BAD IDEA to have enforced style that leads to bugs, as you can see here. I highly suggest editing the configuration to avoid future problems. — VLAZ

-3

first, you must declare a new type object has two property first, second

var varaibale = {first:1, second:2};
varaibale.first = 3;
varaibale.second = 4;
console.log(varaibale);
