* Optimised the factorial function. There was previously an unnecessary check for if the number was 0 or 1. * Create WhileLoopFactorial.test.js The test was not present previously. * result *= num * Update WhileLoopFactorial.test.js * testFactorial function * Space for formatting. * should fix the formatting issues. I was having trouble with npx standard, so I just used the online verifier at https://standardjs.com/demo.html
