What is tree shaking in React apps?
Tree shaking is a technique used in JavaScript applications, including React, to eliminate dead code. It helps reduce the bundle size by removing unused exports.
How does tree shaking improve performance?
By removing unused code, tree shaking decreases the amount of JavaScript that needs to be downloaded and parsed, leading to faster load times and improved performance.
Can you give me an example of how to implement tree shaking in a React app?
Sure! To implement tree shaking, ensure you're using ES6 module syntax (import/export) and a bundler like Webpack or Rollup that supports tree shaking.
Are there any limitations to tree shaking?
Yes, tree shaking may not work effectively with CommonJS modules or if the code is not structured properly. It's best with ES6 modules.
