                generator methods supported
              
          
Method
Description
Common Use


next(value)
Resumes the generator’s execution from where it paused at the last yield. Optionally passes a value into the generator, which becomes the result of the yield expression.
To continue normal execution.


throw(error)
Throws an error inside the generator at the point it was paused. If not caught with a try/catch, it will propagate outside the generator.
To handle Promise rejections or inject errors.

                When to use generators and async/await
              
          
Scenario
Use Generators
Use Async/Await


Processing large or infinite data streams
✅ Ideal - allows lazy evaluation and efficient iteration.
❌ Not suitable - executes eagerly and expects finite results.


Controlling execution flow manually
✅ Best choice - gives precise pause/resume control via next() and yield.
❌ Engine controls execution automatically, limited manual control.


Simplifying asynchronous workflows
⚠️ Possible with helpers like run(), but verbose.
✅ D

                Practical differences between generators and async/await
              
          
Feature / Aspect
Generators
Async/Await


Control
Fine-grained, manual control via next()
Automatic, sequential execution of awaited Promises


Use Case
Iteration, lazy evaluation, custom flow control
Simplifying asynchronous code readability and sequencing


Syntax Complexity
Requires helper or loop for async flows
Native, straightforward, built-in error handling


State Management
Maintains execution context, can pause/resume multiple times
Maintains context until function completes; no manual pause/resume


Memory / Laziness
Can produce values lazily, on demand
