As a web developer, you’re always looking for ways to optimize your applications and deliver the best possible experience to your users. Two powerful techniques that can help you achieve this are tree shaking and dead code elimination.
In this article, we’ll dive into these concepts and explore how you can leverage them to create more efficient and performant JavaScript applications.
What is Tree Shaking?
Tree shaking, also known as dead code elimination, is a process that removes unused code from your final bundle.
It works by statically analyzing your code and identifying the functions, variables, and modules that are actually being used in your application. The unused code is then removed, resulting in a smaller and more optimized bundle.
This is particularly useful when working with modern module systems like ES6 modules (ECMAScript 2015), which provide better support for static analysis and tree shaking compared to older module systems like CommonJS.
