javascript ES6 - 解构数组和交换值

Posted 2021-05-04

let inRing = 'Hulk Hogan';
let onSide = 'The Rock';

console.log(inRing, onSide);
/* This might look a bit funky but what's happening is pretty simple: On the right
hand side we've got an array with the original values. As we give an array, we can 
destructure it, which we do on the lefthand side. We destructure the array renaming
the `onSide` value to `inRing`and the `inRing` value to `onSide`*/
[inRing, onSide] = [onSide, inRing];
console.log(inRing, onSide);
