JavaScript Classes #3: Static Methods - JavaScript OOP Tutorial

In JavaScript you can define "static methods" or "static functions" which are functions that are defined on a class but do not actually require an instance of that class to be created.

In most cases, static methods are "helper methods" or used for creating instances of that class.

In this video I take you through a simple example of how you can define static methods on a class - we create a method used to compare two instances to give a result.

Hey Dom,
Great videos. Thank u.

I finally figured out the ways to use static methods, but still can't imagine easily when should I use that in real life :0

[jamesdong]

Thank you so much. Very very clear and helpful.
What's the common usage of this static method in the more complex cases?

[kevingreetham]

Would it be easier to have a class of utility methods instead of including them in the square class? If “this” is not ever used, what benefit do we have of including them in the same class?

[montebont]

Good explanation as always! Thanks!
But I'm not so sure if this a good approach from a more "abstract" point of view. IMHO properties "are" things with a value. Functions / methods in OOP "do" stuff with properties and the function's parameters. I know that at the end of the day it all boils down to the same in Javascript. But from a working programmer's point of view: I do not see the added value. It works but does not really help to keep your code "clean". But I appreciate all comments about potential benefits. Always willing to learn ;-)
