JavaScript: Functions & Arrays in JavaScript
14 Videos | 1h 50m 13s - Includes Assessment
- Earns a Badge
Learners will discover ways to define and use functions in Javascript, where functions are considered first-class members, in this 14-video course. Explore features of arrays in Javascript, as well as their role in functions. Key concepts covered here include the basic functions and how to invoke them in Javascript; recognizing how var, let, and const keywords affect accessibility of variables in Javascript functions; and how to distinguish between var and let keywords when it comes to scope of variables. Learn to define functions by using concise syntax in ES6 specifications for Javascript; learn to manage errors in an application, whether raised by Javascript or by your own logic using try, catch, and finally blocks; and learn how to create arrays and access and iterate over their elements. Next, learn to use rest parameter syntax to create functions; use the spread operator to expand the contents of arrays; and break down and access components of arrays with array destructuring. Finally, learn how to generate deep and shallow copies of arrays and add and remove array elements.
