JavaScript: IndexOf() vs Includes() |
As a JavaScript developer, it's important to understand the differences between the indexOf() and includes() methods when working with arrays. In this video, we'll explore these methods in depth and discuss when to use each one.
We'll start by explaining how indexOf() and includes() work, and show examples of how to use each method to search for a specific value in an array. We'll then discuss the differences between the two methods, including how they handle the case of searching for an object or a value that appears more than once in the array.
Next, we'll cover some best practices for using indexOf() and includes(), including how to handle edge cases where the value being searched for is not present in the array.
Finally, we'll wrap up by discussing some use cases for each method, and when it makes sense to choose one over the other.
By the end of this video, you'll have a solid understanding of the differences between indexOf() and includes() in JavaScript, and be equipped to make informed decisions about which method to use in different scenarios
