[HIGH] Uses JavaScript optional chaining

Type: too-new
Location: https://ontario.ca/libraries/ontario-interactive-table/dist/ontario-interactive-table.js:1
Message: Feature may be too new for target browsers (14.7% unsupported).
Why it matters: Optional chaining improves readability and safety, but very old browsers require transpilation.
Recommendation: If older browsers are in scope, transpile this syntax and serve appropriate bundles.
Can I Use feature: mdn-javascript_operators_optional_chaining
Unsupported target share: 14.7%
Compatibility source: mdn-bcd
Compatibility note: Can I Use feature 'mdn-javascript_operators_optional_chaining' unavailable; used MDN fallback.
Unsupported targets: and_qq 14.9, and_uc 15.5, kaios 3.0-3.1, kaios 2.5, op_mini all
MDN: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Optional_chaining

[HIGH] Uses nullish coalescing operator

Type: too-new
Location: https://ontario.ca/libraries/ontario-interactive-table/dist/ontario-interactive-table.js:1
Message: Feature may be too new for target browsers (14.7% unsupported).
Why it matters: Nullish coalescing can simplify defaults while avoiding falsy-value bugs, but legacy browsers need transpilation.
Recommendation: Transpile this syntax for older browser support or gate usage to modern bundles only.
Can I Use feature: mdn-javascript_operators_nullish_coalescing
Unsupported target share: 14.7%
Compatibility source: mdn-bcd
Compatibility note: Can I Use feature 'mdn-javascript_operators_nullish_coalescing' unavailable; used MDN fallback.
Unsupported targets: and_qq 14.9, and_uc 15.5, kaios 3.0-3.1, kaios 2.5, op_mini all
MDN: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Nullish_coalescing

[HIGH] Uses document.write

Type: deprecated-pattern
Location: https://ontario.ca/libraries/ontario-interactive-table/dist/ontario-interactive-table.js:1
Message: Legacy pattern relies on a deprecated web platform feature.
Why it matters: document.write can block parsing, hurt performance, and create maintainability and security risk.
Recommendation: Replace with DOM APIs or server-side rendering patterns that avoid parser-blocking behavior.
Can I Use feature: documentwrite
Unsupported target share: 14.7%
Compatibility source: mdn-bcd
Compatibility note: Can I Use feature 'documentwrite' unavailable; used MDN fallback.
Unsupported targets: and_qq 14.9, and_uc 15.5, kaios 3.0-3.1, kaios 2.5, op_mini all
MDN: https://developer.mozilla.org/docs/Web/API/Document/write

[LOW] Detects legacy jQuery usage

Type: legacy-modernization-opportunity
Location: https://ontario.ca/libraries/ontario-interactive-table/dist/ontario-interactive-table.js:1
Message: Pattern has modern native alternatives that may reduce code weight.
Why it matters: Many DOM tasks historically handled by jQuery are now covered by standard APIs.
Recommendation: Evaluate whether targeted vanilla replacements can reduce dependency and improve startup performance.
Can I Use feature: queryselector
Unsupported target share: 0.0%
Compatibility source: caniuse
MDN: https://developer.mozilla.org/docs/Web/API/Document/querySelector
