We have an array of Rectangles called rectangleArray and a function updateRectangle (rect) that takes a single rectangle as a parameter and changes its color to a random color. How can we easily change the color of every rectangle inside rectangleArray?

Following are the code

for (var k = 0; k< rectangleArray. length; k++) / / iterting the loop

{

updateRectangle (rectangleArray[k]); / / update the rectangle color

}

Explanation:

In the given answer we have iterate over the loop will iterated until the length of rectangle array size-1 In every value of k, we have called the update rectangle function which changes the color of the rectangle of a rectangle class
