Bundler

ELI5 — The Vibe Check

A bundler is the robot that smashes all your separate JavaScript files, CSS, images, and random imports into one (or a few) neat packages that the browser can actually digest. It's basically a food processor for your code.

Real Talk

A bundler is a build tool that resolves a dependency graph starting from entry points, transforms source files (transpiling, compiling), and emits optimized output bundles for the browser. Popular bundlers include Webpack, Vite, Rollup, and esbuild.
