Constructor methods requirement in classes

I just have little question. When are constructor methods not required in a class? I only thought of one instance of this which is one when we don't need any properties, anything else?

From what I've gathered, the constructor method is typically used for calling super and for initializing props. Initializing props in the constructor could avoid potential errors downstream in the code if you forget to initialize for some reason. You can also use a constructor method to set default values when initialized.

That being said, I don't think that constructor methods should be used unless it's really necessary to do so.

What is 'super'? Also, how can it be not necessary to use the constructor method? Sorry, I just started to learn OOP so I don't know much.
