That will give you an error: "Uncaught ReferenceError: Console is not defined". That's because you must spell "console" with lowercase "c".
Also, console.log(5/2) will print 2.5 (you can try it yourself here on SoloLearn), BUT console.log(5/2) will actually be equal to "undefined".
It might sound crazy for beginners, but try doing something like "let x = console.log(5/2)". Now if you execute "console.log(x)", "undefined" will be printed.
