This course will teach you a deep understanding of arrays and objects in JavaScript, and how to use them to solve real-world tasks.

Arrays and objects are everywhere in JavaScript, and for that reason many developers use them without really understanding them. A clear-headed understanding of how they operate behind the scenes is sure to make you a much more competent and respected developer. In this course, Arrays and Objects in JavaScript, you’ll learn to understand and leverage the power of arrays and objects on both the front and backend. First, you’ll explore JavaScript objects in depth, gaining an appreciation for the subtle ways they behave differently from other programming languages. Next, you’ll discover the full capabilities of arrays in JavaScript, including the complete set of methods for array manipulation. Finally, you’ll learn how to iterate through arrays like a pro, getting familiar with the methods recently introduced to JavaScript that help you write more functional code. When you’re finished with this course, you’ll have the skills and knowledge of JavaScript needed to utilize objects and arrays in your code and discuss them lucidly.
