# Learn Basic Algorithmic Thinking by Building a Number Sorter - Step 38

### Tell us what’s happening:

I tried different ways, but I’m still getting it wrong. Here are the following ways I tried: j = j + 1, array[j] = array[j + 1], array[j] = j + 1.

<!-- file: index.html -->

/* file: styles.css */

/* file: script.js */
// User Editable Region

const insertionSort = (array) => {
for (let i = 1; i < array.length; i++) {
const currValue = array[i];
let j = i - 1;

while (j >= 0 && array[j] > currValue) {
let j = j + 1;
j--;
}
}
}

Using let here you’re trying to redeclare the variable j. Also, you shouldn’t be incrementing j, but assigning the array value at index j as the value of the next item in the array.

I tried array[j] = array[j + 1]. I think I got it right, but I got it wrong.

Your assignment is just back-to-front now.

Now I got it, I should’ve switched the order.
