Known issues

gotchaLark_JS expects a Lark object, not a string grammar directly.

fix

Instantiate Lark first, then pass it to Lark_JS.

affects: all

gotchaThe generated JavaScript requires a runtime (lark.js) on the client side.

fix

Include the lark.js runtime in your HTML/Node project (available via npm).

affects: all

deprecatedSome Lark grammar features (e.g., dynamic terminals) may not be fully supported in JS generation.

fix

Check the lark-js documentation for supported grammar features.

affects: <=0.1.4
