Tree shaking
open-in-new
<p>In <a href="/facts/Computing/Kghtm9fX">computing</a>, tree shaking is a <a href="/facts/Dead_code_elimination/waQRsajr">dead code elimination</a> technique that is applied when optimizing code. Often contrasted with traditional single-library dead code elimination techniques common to minifiers, tree shaking eliminates unused functions from across the bundle by starting at the entry point and only including functions that may be executed. It is succinctly described as "live code inclusion". </p>
