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

[Sunpius]

Tell us what’s happening:

<— 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) {
 // this is what i thought was required but didn't work
    array[j + 1 ] = array[j];
 j --;

}

}
}
—>
Before decrementing j, assign the value at j to the index j + 1

this is what i have tried with diff approach but it seems i don’t understand well the question

j --;

The -- operator should be touching the variable.

I was really stranded and deeply thinking about it the whole night thanks for being so observant about the “space” that is something that needs a carrot eater with young eyes like you
