Under Active Development
🚀 Coming SoonClosures & Memory Lifecycle Simulator
Visualize how nested functions retain live pointers to outer Activation Objects in Heap memory after execution contexts pop.
✨ Upcoming Simulation Highlights
📦
Function [[Scope]] Internal Slot Pointers
Inspect the static sealing of outer environment records into the [[Scope]] slot during function definition.
🧹
Closures & Garbage Collection (GC)
Understand root reachability: why standard AOs get swept while closures maintain live heap references.
🔄
For-Loop var Bug vs let Block Closures
Compare single shared VariableEnvironment (var) vs per-iteration fresh Declarative ER creation (let).
