About course JS: Functions

Functions is a powerful tool with a wide range of possibilities. This course is designed to help you get to grips with the functions for real. Everything before this course is just the tip of the iceberg.

In this course, we will learn how to create functions so that code is predictable and convenient. Let's examine the handling of collections and see how functions are used in libraries and modern web frameworks.

Basic concepts of the course:

  • Net functions and side effects. Determinacy.
  • Scope and closure
  • Spread and rest operators
  • Objects of the first kind
  • Higher order functions
  • Functional programming

The topics and features listed above are not always present in a JS developer's daily routine (and even more so in other languages), but it's important to be aware of them. First, the approaches covered in this course are not specific to JavaScript. Knowing them will make it much easier for you to switch to other languages. Secondly, working with functions will significantly boost your programming skills.
