Error Boundary vs Try…Catch
- Scope: Error boundaries in React are primarily focused on handling errors within UI components, while try…catch blocks in JavaScript can handle errors in any JavaScript code.
- React vs JavaScript: Error boundaries are specific to React and are used to handle errors within React components, while try…catch is a core feature of JavaScript and can be used in any JavaScript application.
- Granularity: Error boundaries in React provide a way to handle errors at the component level, offering more granular control over error handling compared to try…catch blocks, which operate at the block level within JavaScript code.
Error boundaries in React are a special mechanism for handling errors within React components, while try…catch blocks in JavaScript are a general-purpose feature for handling errors in any JavaScript code.
When Should You Use Error Boundary?
Use error boundaries in React when you want to gracefully handle errors in UI components and prevent crashes from affecting the whole app.
When Should You Use Try…Catch?
Use try…catch in JavaScript for handling errors in synchronous code or functions, especially when you’re dealing with operations that might throw exceptions, like accessing properties of an object that might be null or undefined.
How can you use error boundaries to handle errors in a React application?
Error boundaries are React components that detect JavaScript errors anywhere in their child component tree, log them, and display a fallback UI rather than the crashed component tree. Error boundaries catch errors in rendering, lifecycle functions, and constructors for the entire tree below them.
