noasync/await vs. Promise Chaining in JavaScript

Asynchronous programming in JavaScript has evolved significantly, offering multiple paradigms to handle asynchronous tasks efficiently. Among the most prevalent methods are “async/await” and Promise chaining with “.then()”. Understanding their nuances and practical implications is pivotal for writing efficient, readable, and maintainable asynchronous code.

Context

During a recent discussion with a senior developer, the topic of “async/await” versus “Promise chaining” emerged, specifically in the context of reverting database operations upon failure.

I advocated for “async/await, praising its simplicity and consistent outcomes. However, I acknowledged occasional challenges with “Promise chaining”, leading to unexpected results in certain programs.

In contrast, the senior developer favored “Promise chaining”, highlighting its potential to revert database operations if a single task fails. Accepting my lack of in-depth knowledge, I acknowledged the effectiveness of “Promise chaining” in handling these scenarios, despite its occasional complexities.

So i took it upon myself to figure out whether this is true or not.

“async/await”: A Synchronous-like Asynchronous Paradigm

Introduced in ES2017, “async/await” brought a significant paradigm shift to asynchronous JavaScript programming. It allows developers to write asynchronous code in a…
