数组解构并分配给类字段值？

Question

class ALU {  constructor (x, y) {    this.zx = '0' // Zero the x input    this.nx = '0' // Negate the x input    this.zy = '0' // Zero the y input    this.ny = '0' // Negate the y input    this.f = '0' // Function code: 1 for Add, 0 for And    this.no = '0' // Negate the output  }  ...  setControlBits (controlBits) {    this.zx = controlBits[0]    this.nx = controlBits[1]    this.zy = controlBits[2]    this.ny = controlBits[3]    this.f = controlBits[4]    this.no = controlBits[5]  }  ...}如何简洁地编写这段代码？就像我们可以解构数组并将其分配给类字段值吗？

Answer 1

试试这个。

function Foo(list) {

    [this.x, this.y] = list;

}

foo = new Foo([1, 2]);

console.log(foo.x);

console.log(foo.y);
