销毁工作。 在两个不同的变量中分配对象及其子对象

Question

There is a nested object:

var a = {
  b: {
   c: 'some value'
  }
}

Is there a way to make a destructing assignment to get following two variables with only one statement?

var c = 'some value';
var b = {c : {'some value'}}

Answer 1

Just destructure the two parts separately.

var { b, b: { c } } = a;

Which compiles to the following code with Babel .

var _a = a;
var b = _a.b;
var c = _a.b.c;

Answer 2

Try

 var a = { b: { c: 'some value' } } var [c, b] = [abc, ab] console.log(c, b)
