Parcel (prcl)

Parcel is an ultra-fast JavaScript bundler designed for development speed, v0.4.0, with no release cadence (sporadic). It avoids parsing JS fully, working mostly by concatenation with a few simple rules (no dynamic requires, no non-constant module names). Key differentiator: sub-10ms rebuilds, faster than Browserify or FuseBox by an order of magnitude, but lacks advanced features like tree-shaking. Ideal for rapid iteration during development, not production builds. ESM-only; CommonJS require() is used but only with static strings.
