JavaScript中的匿名数组分配

Question

Firefox (v 16) has no problem with this anonymous array assignment from a function:

var x = 0; var y = 0;
[x,y] = incr1(x,y);  // x,y now both equal 1
function incr1(x,y) {
    return [x+1,y+1];
}

using the developer tools in Chrome (v 18) on the other, it hand complains "Uncaught reference error: invalid left hand side in assignment"

Answer 1

Firefox是唯一支持该语法的浏览器。
