+# Deno API Migration Tasks
+
+## Overview
+Migrate javascript.rs from old `deno` crate (custom fork) to modern `deno_core 0.371` + `deno_runtime 0.229`.
+
+## Current Status
+- ✅ Dependencies updated in Cargo.toml
+- ✅ Build system resolved (globals.h generated)
+- ✅ emacs-sys compiles
+- ⏳ **NOW**: Migrate ~40 old Deno API calls in javascript.rs
+
+## Specific Changes Required
+
+### 1. Update Imports (Lines ~1-25)
+**OLD**:
+```rust
+// No explicit deno imports - implicitly using custom fork
+```
+
+**NEW**:
+```rust
+use deno_core::{JsRuntime, RuntimeOptions, ModuleSpecifier};
+use deno_runtime::{
+    worker::{MainWorker, WorkerOptions},
+    permissions::PermissionsContainer,
+};
+use deno_ast::MediaType;
+```
+
+### 2. Remove ProgramState (Line 103, 219-224)
+**OLD**:
+```rust
+program_state: Option<Arc<deno::program_state::ProgramState>>,
+```
+
+**NEW**:
+Remove this field entirely. Configuration now handled via WorkerOptions
