What is tree shaking in Webpack?
Tree shaking is a term commonly used in JavaScript bundlers like Webpack to describe the process of removing unused code from your final bundle.
How does tree shaking work in Webpack?
Tree shaking works by analyzing the import/export statements in your code. Webpack identifies which parts of the code are actually used and eliminates the rest during the build process.
Do I need to configure anything for tree shaking to work?
Yes, to enable tree shaking, you should ensure that your code is using ES6 module syntax (import/export) and set the mode to 'production' in your Webpack configuration.
Can tree shaking reduce the size of my bundle significantly?
Yes, tree shaking can significantly reduce bundle size, especially in large applications with many dependencies, by removing dead code.
