Use Destructuring with reassignment to Assign Variables from Objects

Tell us what’s happening:

My code pass two of three assignments and I get this error:
destructuring with reassignment was used

Your code so far

function getLength(str) {
  "use strict";

  // change code below this line
  const length = {length:str.length}; // change this
  // change code above this line

  const {length:len}=length; // you must assign length to len in line
 return len

Link to the challenge:

here it is

 const {length:len} = str;
1 Like

it is equal to const len = str.length;

I do not understand why this is so, it follows from the example that it should be like the one described above by SaeidAshian

other example:

“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;”

You do not understand why what is so?

I search on forum and now I understand.
I should first look for information later, write, I’m sorry :slight_smile:
