Accessing 'type' of ESTree AST nodes is megamorphic. Doing this repeatedly in an if-cascade in a hot loop is very costly. This CL reduces the time it takes to parse and format two large bundles (3.8MB and 11MB) from: ``` Formatting ./blitz.7dbe22a9.js (median): 1510.70 ms Formatting ./workbench.web.main.js (median): 5784.81 ms ``` to ``` Formatting ./blitz.7dbe22a9.js (median): 1365.15 ms Formatting ./workbench.web.main.js (median): 5023.51 ms ``` R=bmeurer@chromium.org Bug: 333945853 Change-Id: If6b0ff55bc0f5ea2f1f1b7b1fc4523fbcd835952 Reviewed-on: https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/5463982 Commit-Queue: Simon Zünd <szuend@chromium.org> Reviewed-by: Benedikt Meurer <bmeurer@chromium.org>

Source mirrors
DevTools frontend repository is mirrored on GitHub.
DevTools frontend is also available on NPM as the chrome-devtools-frontend package. It's not currently available via CJS or ES modules, so consuming this package in other tools may require some effort.
The version number of the npm package (e.g. 1.0.373466) refers to the Chromium commit position of latest frontend git commit. It's incremented with every Chromium commit, however the package is updated roughly daily.
