Createcontext react12/29/2023 I like to think of a function as a block of code that performs a function with either zero or any number of arguments passed to it. Ideally, a function’s arguments are used for its operation. In React, we can use props to make our components communicate.Ĭomponents are like JavaScript functions that can accept any number of arguments. Reusing components comes with the benefits of DRY code components usually have some data or functionality that another component needs, for example, to keep components in synchronization. You want to avoid duplicate logic and prevent over-abstraction. However, components are also meant to be reusable. If anything in your application breaks, you can easily identify where things went wrong using fault isolation. ![]() With components, we can isolate individual parts of a larger application, providing a separation of concern. While your application might start out with just a single component, as it grows in complexity, you must continually break it up into smaller components. While this article is easy to follow and understand, we won’t provide detailed explanations of basic JavaScript and React concepts as we go through examples. This article assumes you have a solid grasp of JavaScript and an intermediate level knowledge of React itself. First, we’ll cover what prop drilling is and why we should avoid it. In this tutorial, we’ll explore how we can use React Context to avoid prop drilling. The React Context API, introduced in React v.16.3, allows us to pass data through our component trees, giving our components the ability to communicate and share data at different levels. ![]() Component re-rendering is especially damaging when developers need components to communicate with each other in a process known as prop drilling. Check out this article to ensure that you don’t overuse React Context.ĭespite React’s popularity, one of the biggest obstacles developers face when working with the library is components re-rendering excessively, slowing down performance and harming readability. Editor’s note: This article was last updated on 24 March 2023 to compare the process of using React Context with class-based components vs.
