# Selection Sort

The second sorting method we used is called **Selection Sort**.

## Completed Code

```javascript
function selectionSort(arr) {
  var minIdx, temp,
    len = arr.length;
  for (var i = 0; i < len; i++) {
    minIdx = i;
    for (var j = i + 1; j < len; j++) {
      if (arr[j] < arr[minIdx]) {
        minIdx = j;
      }
    }
    temp = arr[i];
    arr[i] = arr[minIdx];
    arr[minIdx] = temp;

  }
  return arr;

}
console.log(selectionSort([207, 150, 71, -25, 369, 246, -13, 22, 150]));
```

## Explanation

1. `selectionSort()` searches for the element with the **lowest value**.
2. The lowest value is **-25** with an index of **3**. &#x20;
3. -25 swaps places with the first element in the array **207**. This way we now have the lowest value starting off our array.
4. Repeat the process, finding the next smallest value and putting it to the right of **-25**.
5. Repeat the process until the array is properly sorted.

## Variables Explanation

* `minIdx` - the index of our smallest value. It is initially set to the first element in our array.
* `temp` - a temporary variable to easily allow the value of `arr[minIdx]` to change.
* `i` and `j` - the indexes of the elements that are being compared.  &#x20;
