Left-hand side with object attributes substituted by value in array destructuring
0xc22b opened this issue · comments
Describe the bug
Using array destructuring with object attributes on the left-hand side:
const bin = {
hasMore: false, hasDisorder: false,
};
[bin.hasMore, bin.hasDisorder] = [true, true];
It gets compiled into:
[!1, !1] = [
!0,
!0
];
which is incorrect: SyntaxError: Invalid destructuring assignment target
Input code
export function test() {
const bin = {
hasMore: false, hasDisorder: false,
};
[bin.hasMore, bin.hasDisorder] = [true, true];
}
