JS: Introduction to Object Oriented Programming (OOP)

Included in the course

What you'll learn

• Competently use the context of this depending on the situation
• Describe subject matter entities using objects, prototypes, and classes
• Understand how objects work in JavaScript at the lowest level
• Use exceptions in your code

Description

JS - multi-paradigm programming language with support for object-oriented programming. This course begins an introduction to the basic concepts and syntactic constructs inherent in OOP. Encapsulation and data hiding are covered. Features of the behavior of this are discussed, prototypes and exceptions are studied.
