The aim of this puzzle: Draw 4 randomly colored boxes in a 2 by 2 grid.
Walkthrough of the solution:
pickRandom() randomly selects a value from a list, while
color holds a list of different colors.
pickRandom(color) will randomly select one color, such as blue or purple.
To make a box have a random color,
pickRandom(color) needs to go inside
drawBox(pickRandom(color)). This is called Call Nesting; when a function —
pickRandom() — is put inside another function —
drawBox(). The function
pickRandom(color) runs and a color is selected, this color is then “given” to the
If, for example, the random color selected was red, the computer would “see”
drawBox(red) rather than
drawBoxes(pickRandom(color)). This means a red box would be drawn.
To make a 2 by 2 grid of boxes, you need a row of 2 boxes side by side, then a new line, then 2 more boxes side by side.
