2. Challenge

The Audience Wave is an example of metachronal rhythm achieved in a packed stadium when successive groups of spectators briefly stand, yell, and raise their arms. Immediately upon stretching to full height, the spectator returns to the usual seated position.

Your task is to create a function that turns a string into an Audience Wave. You will be passed a string and you must return that string in an array where an uppercase letter is a person standing up.

The input string will always be lower case but maybe empty. If the character in the string is whitespace then pass over it as if it was an empty seat.

2.1. Examples

wave("hello") // returns ["Hello", "hEllo", "heLlo", "helLo", "hellO"]

2.2. Testing your solution

To test your solution, run npm i in the root directory and then run npm t to run the automated tests.

2.3. Submitting your solution
