This course will teach you the ins and outs of JavaScript functions, which are essential for developing complex frontend or backend web applications in JavaScript.
Functions are a fundamental pillar of any programming language. Without functions, programs would not be able to do anything. In this course, Functions in JavaScript, you’ll learn to use functions effectively by leveraging all their capabilities in the right circumstances. First, you’ll explore how to define and invoke functions. Next, you’ll discover the various ways to pass parameters to a function. Then, you'll understand what methods, getters, and setters are, and how they can encapsulate behavior. Finally, you’ll learn to use functions asynchronously and deep dive into advanced concepts such as scope and closures. When you finish this course, you’ll have the skills and knowledge of functions needed to develop complex backend or frontend applications in JavaScript.
