JS objects keys explained simply
1. In JavaScript, keys like 1 are converted to "1". So obj[1] and obj["1"] are actually the same key. 2. Since both point to "1", the latest assignment overrides the previous one. 3. Key order in objects Number-like keys → come first (in numeric order) Other strings → come next (in insertion order) Symbols → come last
