JavaScript is AsynchroWAT?
summary
A developer story starts with integrating Stripe into Salesforce and discovering JavaScript callbacks block work because responses arrive later; code examples show a blocking AJAX pattern, then a nested callback hell implementation with setTimeout-based waits and ad hoc error checks, a promise-based rewrite with .then/.catch and a pizza promise example, and finally an async/await refactor that returns Promises and reads synchronously; the hair-care analogy maps each async step and the refactors clearly run and improve readability and error handling.
