JavaScript Arrays and Collections from Pluralsight

ECMAScript 6 introduces some new and powerful ways to handle data. This course will introduce you to working with sets and maps as well as typed arrays so you can easily store and process data within your web apps with more functionality.

At the core of using data collections within JavaScript is a thorough knowledge of sets, maps, and typed arrays. In this course, JavaScript Arrays and Collections, you will learn how to create and apply data collections to your web applications. First, you will understand how to apply more advanced array methods to your current arrays. Next, you will explore how to store unique data using sets. Then you will learn how to store data using key and value pairs with maps. Finally, you will discover how to work directly with binary data using typed arrays. When you are finished with this course, you will have a foundational knowledge of data collections within the JavaScript language that will help you as you move forward to building more efficient web apps.

Software required: A text editor like Sublime or Visual Studio Code.
