Based on upstream JavaScriptKit 0.60.0 with PassiveLogic additions:

• JavaScriptEventLoop.yieldInterval - opt-in time limit for one drain of the job queue, so long-running async work yields to the JavaScript event loop (#26, upstream: swiftwasm#821)

Usage in Package.swift:

.package(
    url: "https://github.com/PassiveLogic/JavaScriptKit",
    exact: "0.60.0-pl.1",
),

If another dependency requires swiftwasm/JavaScriptKit by version range, pin the revision instead, because a version range never matches a pre-release tag:

.package(
    url: "https://github.com/PassiveLogic/JavaScriptKit",
    revision: "b8369d9d8417fa55d64e513c74f5f031a6bd4ec3",
),

Based on upstream JavaScriptKit 0.50.2 with PassiveLogic additions:

• Pointer identity mode (identityMode: "pointer") - opt-in WeakRef-based cache ensuring same Swift heap pointer returns same JS object (=== equality)
• Configuration via bridge-js.config.json - follows exposeToGlobal pattern
• Retain leak fix - balances passRetained on identity cache hits
• Identity mode benchmarks - roundtrip, pool, churn, memory profiling scenarios
• IQR outlier removal - improved benchmark statistics for all benchmarks

Usage in Package.swift:

.package(
    url: "https://github.com/PassiveLogic/JavaScriptKit",
    exact: "0.50.2-pl.1",
),
