![]() ![]() The useContext hook takes the context object as an argument and returns the current value of the context object. You can use the useContext hook inside your component to retrieve the data from the context object. Once you have defined your context object, you can wrap your component tree in a context provider component that provides the data to all its children. This context object can be a plain JavaScript object or a custom class that provides data to your component tree. To use the useContext hook, you must define a context object in your React component. The React useContext hook allows you to access this context object and retrieve the necessary data. A context provider is a component that provides data to all of its children via a context object. The useContext hook is a built-in hook in React that allows you to consume data from a context provider. This can be especially useful when working with complex components requiring access to much data. React useContext hook allows sharing data across a React component tree without passing props down through multiple levels. A Beginner’s Guide to React useContext Hook But before diving into that, we first need to understand what React useContext is and how it works. ![]() We’ll build a simple to-do app to demonstrate using useContext in a real-world scenario and highlight some best practices. Whether you’re working on a small app or a large-scale project, useContext can help you create clean, reusable code that’s easy to maintain. This can significantly simplify your code and make tracking all the data you need to manage easier. However, with React useContext, you can create a vendor context that stores all the necessary information and pass it down to child components as needed. Using the traditional approach of passing state down through props can quickly become unwieldy and difficult to manage. Each vendor has its own inventory and shipping policies, and you need to keep track of all this information to provide accurate pricing and delivery estimates to users. Imagine you’re building an e-commerce website that allows users to purchase products from multiple vendors.
