The arrow function in the shuffle () method is quite short and thus can be simplified to a single line: array.sort ( (a, b) => a.sortVal - b.sortVal) The forEach block above it could also be simplified: array.forEach ( x => x.sortVal = Math.random ()) In this case, x.sortVal would be returned in each iteration but that doesn't make a difference.
