Benchmark: Benchmark function expression vs multiple class constructors with Date()

Tests:

Add a week by instantiating 3 date objects, modifying date
for(i=0; i<100000; i++){ let defaultExpireDate = new Date(new Date().setDate(new Date().setDate() + 1)); return defaultExpireDate; }
Add a week by using anonymous expression with an instantiated Date
for(i=0; i<100000; i++){ let defaultExpireDate = (curDate = new Date(), days = 7) => new Date(curDate.setDate(curDate.getDate() + days)); return defaultExpireDate(); }
