What is Tree Shaking? Tree shaking is an automated optimization process used in software engineering to strip away dead, unused code before an application is launched. By analyzing how code files connect to one another, build tools can safely discard any functions or variables that are never actually called. This process keeps the final application package incredibly lean, ensuring websites load quickly and perform efficiently on all devices.
