Use Destructuring Assignment to Assign Variables from Objects |
Use Destructuring Assignment to Assign Variables from Objects
This challenge requires some intuition about string objects in javascript.
When you create a string object it is based on the following string prototype.
Thus, each string has a length property; genericString = {length: 13}. (This is the only adopted property from the String.prototype.)
Reassign properties using deconstruction.
var basicOjb = {x: 40};
//To reassign 'get the value of the x property of basicObj and place its value into bigX' in ES6:
const { x: bigX } = basicOjb;
consle.log(bigX) // ans = 40
Place the value of the length property of 'str' into len.
