Arrays hold multiple data points, and loops are a great way to iterate over the data with repetitive actions. Just like the foreach method of arrays, the foreach loop is a way to loop through arrays to access and process each array element.

$array = 51,12,31,4,15
foreach ($element in $array) {
  if ($element % 2 -eq 0) {
    Write-Host $element "is" Even
  } else {
    Write-Host $element "is" Odd
  }
}

The foreach keyword is used in the above example, followed by parentheses. Inside the parentheses, the expression $element in $array tells the loop to iterate through each element of $array and set the value of $element to the values in the array. The code output is:

51 is Odd
12 is Even
31 is Odd
4 is Even
15 is Odd

As shown above, in the first loop iteration, $element is assigned the first element in the array, 51. In each iteration to follow, $element is updated with the next $array value.
