Can I Safely \'Fire and Forget\' Promises in Node.js?

Can I fire and forget a promise in node.js (ES7)?

Question:

Is it acceptable to run an asynchronous function without explicitly waiting for it using await in an async function in Babel?

Answer:

Yes, you can run asynchronous functions in parallel without awaiting them, which is known as "fire and forget." However, it's important to consider:

• Unhandled rejections: If the promise is rejected, it will result in an unhandled rejection that can crash your application.
• Clarity and explicitness: It's best practice to be clear and explicit about your expectations for asynchronous tasks.

How to disregard asynchronous tasks:

Depending on the scenario, there are different options to disregard asynchronous tasks:

• Throw away the result: Use void (await someAsyncFunction()) or simply omit void for expression statements.
• Ignore exceptions: Use someAsyncFunction().catch(function ignore() {}).
• Execute in parallel: Use Promise.all([someAsyncFunction(), someOtherAsyncFunction()]) to execute multiple asynchronous functions in parallel, discarding the result from the first function.
