Question 1

How do I use p-lazy with async/await?

Accepted Answer

Simply await a p-lazy promise like a regular Promise. For example, `const result = await new PLazy(resolve => { heavyOp(); resolve(); });` defers execution until the await, as shown in the README usage.

Question 2

p-lazy vs native Promise: which should I use?

Accepted Answer

Use p-lazy when you need to avoid unnecessary computation by delaying execution until the promise is consumed. For immediate execution or simple cases, stick with native Promise to keep things lightweight.

Question 3

Does p-lazy work in Node.js and browsers?

Accepted Answer

Yes, it's a JavaScript library that relies on standard Promise APIs, so it should function in both Node.js and modern browsers. The install via npm confirms Node.js support, and browser compatibility is implied.

Question 4

What are the performance benefits of p-lazy?

Accepted Answer

It prevents wasteful computation by not running heavy operations until the promise is actually needed. This can reduce memory usage and CPU load in apps with conditional or lazy-loaded promises.

Question 5

Can I cancel a p-lazy promise?

Accepted Answer

No, p-lazy doesn't include cancellation features. For that, you'd need a library like p-cancelable, which is mentioned as a related project in the README for advanced use cases.

Question 6

How to handle errors with p-lazy promises?

Accepted Answer

Error handling is identical to native promises: use .catch() or try/catch with async/await. The lazy execution doesn't affect error propagation; it just delays when the executor runs.
