JavaScript classes give us a bunch of nice features that make the code we write clean and concise, while also performing at or near the same speed as if we wrote directly to the prototype. One nice feature is the inclusion of static member variables and static member functions.
While there is not much of a difference, it does allow us to write functions that cannot be accessed by the member functions (they can still be accessed, but it is a lot harder) and it can provide a good tool for grouping utility functions to that specific class. An example of static functions and variables is shown here:
class newItem { static e() { console.log(this); } static f = 10;}newItem1.e() //TypeErrornewItem.e() //give us the class
