7. Advanced JavaScript

Learning Objectives

By the end of this chapter, you will be able to:

• Test simple scripts using Node.js REPL
• Construct objects and arrays and modify their content
• Use object methods and operators to get information about the object
• Create simple JavaScript classes and classes that inherit from other classes
• Use advanced built-in methods from Math, RegEx, Date, and String
• Manipulate data in JavaScript using Array, Map, and Set methods
• Implement Symbols, Iterators, Generators, and Proxies

In this chapter, we will work with arrays, classes, and objects in JavaScript, and then we will use inheritance and built-in methods in common JavaScript classes to simplify our code and make it highly reusable.
