解析存储在object属性中的数组的赋值

Question

say I have an object:

{ foo: 1, bar: 'a', baz: [1,2,3] }

how to assign the value of baz to get the head and the tail of the array?

I mean so that the effect is the same as that of the code below, except for I do not want to use the extra variable baz :

{ baz } = obj;
[head, ...tail] = baz;

I know I can say [head, ...tail] = obj.baz but my question is about the syntax.

Answer 1

You can for instance do

let {baz: [head, ...tail]} = obj;

by combining the patterns together.
