📵 Understanding The Secret Power of Generators

#js #generators #guide

When to Choose Which?

Use generators when:

— You need to manage complex control flows with precision.
— Memory efficiency is critical, and you want to generate values on demand.
— You’re implementing patterns like state machines or lazy iteration.

Use promises when:

— You’re handling simple asynchronous operations.
— You need to work with concurrent tasks.
— You prefer simpler, more straightforward error handling.

Best Practices for Using Generators:

1. Keep It Simple
Generators can add complexity to your code, so use them judiciously. If a task can be easily handled with promises or async/await, there’s no need to reach for generators.

2. Combine with Promises for Maximum Effect
Generators and promises are not mutually exclusive. In fact, they can complement each other beautifully. For instance, you can use a generator to structure your async flow and promises to handle the actual asynchronous operations.

3. Mind the Iteration
When using generators for iteration, always be mindful of when to stop. An infinite loop in a generator can be a real headache if not properly managed. Ensure you have clear exit conditions if your generator has the potential to run indefinitely.

4. Test Thoroughly
Given the unique execution flow of generators, thorough testing is crucial. Ensure that all possible execution paths are covered, including edge cases where the generator might yield unexpectedly or be terminated early.

5. Leverage TypeScript for Type Safety
Since you’re writing in TypeScript, make sure to define the types for your generator functions. This adds an extra layer of safety, helping you catch potential issues at compile time.

🚯 Magic of Generators

Generators: Advantages

— Fine-Grained Control: Generators give you the ability to pause and resume function execution at will. This can be a game-changer in scenarios like lazy evaluation, custom iteration logic, or complex control flows.

— Memory Efficiency: Since generators produce values on demand, they are highly memory-efficient, making them perfect for handling large datasets or streams.

— Readable Asynchronous Code: While async/await has largely supplanted many asynchronous handling methods, generators still offer a unique combination of readability and control, making complex asynchronous flows easier to manage.

📵 Promise.try()

#js #promises

What is Promise.try()?
In essence, Promise.try() is a static method that wraps any function — be it synchronous, asynchronous, value-returning, or exception-throwing — into a Promise. It effortlessly handles both sync and async functions while automatically catching synchronous exceptions, preventing error leaks. 🎭

Advantages of Promise.try()
1 — Unified Handling: Seamlessly manages both synchronous and asynchronous functions, resulting in cleaner code. 🧼
2 — Exception Handling: Automatically captures synchronous exceptions, making error handling more intuitive and preventing oversights. 🕵️‍♂️
3 — Code Simplicity: Compared to traditional methods, Promise.try() enhances code readability and maintainability. 📚
