The US$4000 JavaScript Interview Question Nobody Could Answer

A tech interview challenge offered 0.1 BTC for answering a JavaScript ES5 to ES6 breaking change question. The author argues the correct answer is that the question itself is misguided because interviews should assess software design and domain modeling, not language trivia. The piece critiques common tech interviews for favoring language-specific knowledge over fundamental software engineering skills, leading to groupthink and low-value code. It advocates for decoupled domain models that survive language updates, and warns that over-coupling to technology creates liabilities. The real value is in business-focused software design, not in memorizing language quirks.
