ay you have a function primitiveMultiply that in 20 percent of cases multiplies two numbers and in the other 80 percent of cases raises an exception of type MultiplicatorUnitFailure. Write a function that wraps this clunky function and just keeps trying until a call succeeds, after which it returns the result. Make sure you handle only the exceptions you are trying to handle. class MultiplicatorUnitFailure extends Error {} function primitiveMultiply(a, b) { if (Math.random() < 0.2) { return a * b; } else { throw new MultiplicatorUnitFailure("Klunk"); } } function reliableMultiply(a, b) { // Your code here. } console.log(reliableMultiply(8, 8)); // → 64
