Destructuring assignment works fine for "var" and "let" but not for "const".
Reproducible: Always
Steps to Reproduce:
const [a, b] = [1, 2];
Actual Results:
a and b are defined as consts whose values are "undefined".
Expected Results:
a and b are defined as consts and a == 1 and b == 2.

My understanding of the compiler work is that:
const [a, b] = [1, 2];
is transformed in:
const a, b;
{
let $0 = [1, 2];
a = $0[0];
b = $0[1];
}
