How do I implement tree shaking in my JavaScript project?

Tree shaking is a technique to eliminate dead code in your JavaScript bundles. To implement it, ensure you're using ES6 module syntax (import/export) and a bundler like Webpack or Rollup.

What configuration do I need for Webpack to enable tree shaking?

In your Webpack configuration, set the mode to 'production'. This enables optimizations including tree shaking. Also, ensure that your code uses ES6 modules.

Can you give me an example of how to structure my code for tree shaking?

Sure! Here's a simple example: create a file math.js with named exports like export const add = (a, b) => a + b;. Then, in your main file, import only what you need: import { add } from './math';.

Are there any limitations to tree shaking?

Yes, tree shaking works best with pure functions and static imports. Dynamic imports or side effects in your modules can hinder the process.
