Execution context, call stack, scope chain, and memory heap in JavaScript

JavaScript creates execution contexts for code execution, uses a call stack for active functions, resolves variables through the scope chain, and stores objects in memory.

  • Contexts track variables and `this`
  • The call stack orders active frames
  • Heap memory holds reference values
