Early review request for "Explicit JavaScript Compile Hints"

[marjakh]

こんにちは TAG-さん!

I'm requesting a TAG review of "Explicit JavaScript Compile Hints".

This proposal introduces a new magic comment that signals to browsers that the functions in a JavaScript file are likely to be needed by the website. This allows the browser to parse and compile them eagerly, which can improve page load times.

• Explainer¹ (minimally containing user needs and example code): https://github.com/explainers-by-googlers/explicit-javascript-compile-hints-file-based
• User research: None
• Security and Privacy self-review: The feature only affects performance; no privacy implications.
• GitHub repo (if you prefer feedback filed there): https://github.com/explainers-by-googlers/explicit-javascript-compile-hints-file-based/
• Primary contacts (and their relationship to the specification):
  • Marja Hölttä, V8 / Google
• Organization/project driving the design: V8 / Google
• External status/issue trackers for this feature (publicly visible, e.g. Chrome Status): None

Further details:

• I have reviewed the TAG's Web Platform Design Principles
• The group where the incubation/design work on this is being done (or is intended to be done in the future): Not set up yet
• The group where standardization of this work is intended to be done ("unknown" if not known): Unknown; as it doesn't change JavaScript semantics, TC39 is likely not the right venue.
• Existing major pieces of multi-stakeholder review or discussion of this design: No artifacts; see https://github.com/explainers-by-googlers/explicit-javascript-compile-hints-file-based/blob/main/README.md#stakeholder-feedback--opposition based on informal discussions.
• Major unresolved issues with or opposition to this design: See above
• This work is being funded by: Google

Thanks in advance!
