Course details

When first learning a programming language, it is imperative to understand how different data structures can be used to store data. Each programming language has its own set of data structures, some of which are unique to that language and others that are standard across multiple programming languages. In this course, software engineer Tiffany Graves introduces you to objects in JavaScript to help you understand how objects are created and used as a data structure. Learn about data structures (what are they and why use them), arrays and objects, creating objects, adding data to objects, and updating and deleting data in objects. Plus, learn when to use objects, the pros and cons of using objects, and get a look at objects in other programming languages.
