Javascript
// rainbowColors.js
// This script iterates through the colors of the rainbow and logs each one to the console.
/**
* An array containing the standard colors of the rainbow in order.
* Each element is a string representing a color name.
*/

/**
* Loop through the `rainbowColors` array.
* The `for` loop is used to access each color by its index.
* `i` starts at 0 and increments until it reaches the total number of colors.
*/
for (let i = 0; i < rainbowColors.length; i++) {
// Access the current color using its index 'i'.
const currentColor = rainbowColors[i];
