They want you to create a function (assigned to the random property) that takes two numbers from an array (so the input is a destructured array) and then uses these two numbers to calculate a random number between them. (Where the randomly generated number lies in the range: inclusive of the smaller value and exclusive of the sum of the two inputs)
