For what purpose do we use classes?

Question

Is it kind of permissions?

Answer 1

You can think of a class as the basic unit of object oriented programming. Everything works by objects holding data, doing 'stuff' and interacting with other objects. But what do our objects look like? How do they behave? Classes define what our objects can do, what data they hold, and how they can interact.

There is an element of permissions I guess, in that some code is restricted and only useable in the situations described in it's definitions.

Answer 2

Classes can be used as templates to build objects. The objects then have access to the class methods and properties.
