What is tree-shaking in JavaScript?
Tree-shaking is a technique used in JavaScript to eliminate dead code, reducing the final bundle size.
How does tree-shaking work in modern JavaScript frameworks?
It works by analyzing the import/export statements in your code to determine which parts are actually used.
Can you give me an example of tree-shaking in action?
Sure! If you import a library but only use one function, tree-shaking removes the unused functions from the final bundle.
What tools can I use to implement tree-shaking?
Popular tools include Webpack, Rollup, and Parcel, which all support tree-shaking out of the box.
