Why might one use JSON?

JSON, or JavaScript Object Notation, is an increasingly standardized way of sharing datasets between Application Programming Interfaces(APIs), databases(for example, MySQL) and different programming languages(PHP and python tend to be popular for server side coding). JSON objects are easily formatted into a desired data structure, which is typically an array of some kind.

What are the four pillars of Object Orientated Programming?

Abstraction - implementation of a class and its methods can be hidden from the outside world. Polymorphism (variables of the same name can be compiled differently in different contexts due to their underlying interface) Inheritance(sub-classes inherit and customize features from their parent/super class) Encapsulation - (data hiding with getters and setters)

Could you describe the easiest way to center the content of a website or web-app you are developing?

Typically, this would be done using the .container class tag, in conjunction with a popular CSS library or framework such as Bulma or Bootstrap.
