Tell us what’s happening:

Your code so far


const s = [5, 7, 2];
function editInPlace() {
 'use strict';
 // Only change code below this line
s = [2, 5, 7];
 // Using s = [2, 5, 7] would be invalid

 // Only change code above this line
}
editInPlace();

Challenge: Mutate an Array Declared with const

Link to the challenge:

Hello~!

Take a look at the example provided in the challenge instructions:

"use strict";
const s = [5, 6, 7];
s = [1, 2, 3]; // throws error, trying to assign a const
s[2] = 45; // works just as it would with an array declared with var or let
console.log(s); // returns [5, 6, 45]

Do you see the line that successfully changes one of the values in the array?

You need to change every place in array separetely.

4

just thinking of how to apply it here

Okay, so let’s look at the expected return value:

s should be equal to [2, 5, 7].

If s[2] = 45 sets the last value of the array to 45, how would we set these three values?

thanks
but still couldn’t get it
this is what i did
s = [2, 5, 7];
but it is not passing the text yet

7

you can’t do this. it literally says that s = [2, 5, 7]; will be invalid. you need to change every place in array separately as they did in the example using s[2] = 45 (they changed the 3d element there, so you can use the same process and change all the numbers in your array)
