JavaScript as a language is heavily asynchronous, with promises being deeply integrated. The inclusion of async/await syntax has massively improved this, making asynchronous code much more readable. Being able to mark methods as async makes it much easier to integrate into existing parts of code, sometimes causing large chains of method calls to become async for a single deep method call. While this is sometimes the best solution, can the overhead of promises pose a problem for hot code?
