What is Promise.try and how could it help in JavaScript programming?

The TC39 proposal for Promise.try in JavaScript aims to simplify the handling of functions that might or might not be asynchronous, without needing to know in advance.

It provides a straightforward way to handle these functions safely by wrapping them in a promise, thus leveraging promise handling methods like .catch to manage any resulting errors.

This method ensures that functions are executed synchronously when possible, offering a performance advantage by not deferring to the event queue unless necessary.

The proposal, drafted by Jordan Harband, is currently at stage 2.7, indicating that it's generally accepted but awaiting further testing and final approval for implementation. The proposed Promise.try function would mirror the behavior of async functions up to the first await, allowing synchronous functions to run immediately and return values or throw errors which are then handled by Promise semantics.

This addition could significantly tidy up JavaScript code, particularly in scenarios where developers are dealing with functions that might not always return promises but want to ensure consistency in handling asynchronous operations.

The adoption of Promise.try would align JavaScript more closely with other programming environments that offer similar functionalities, enhancing its robustness and utility in asynchronous programming.
