Web Development Tutorials

In this lab, we will learn about the useFetch hook in React. This hook allows us to implement the fetch() method in a declarative manner, making it easier to fetch data from APIs and update the component state. We will create a custom hook that takes a URL and options, and asynchronously calls fetch() to update the response, error, and abort state variables.

In this project, we will create a VSCode extension that lets the user adjust the heading level of selected Markdown text.

In this lab, we will explore the concept of functions in JavaScript. We will learn how to define and call functions, pass arguments, and return values. Additionally, we will practice using the isFunction() function to check if a given value is a function. By the end of this lab, you will have a solid understanding of how functions work in JavaScript and how to use them effectively in your code.
