> Like LiveCode's "Pending Messages". Under the hood, JavaScript uses a **call stack**. When you call a function: * The current line is "paused" * The new function is "pushed" onto the stack * When it finishes, it's "popped" off, and execution resumes where it left off It’s *like LiveCode’s message path*, but **more structured and limited**. There’s no visual object hierarchy—just the stack of function calls.
