# No redundant comments Good code already says what it does. A comment that restates the next line in English adds nothing, doubles the maintenance surface, and is a classic tell of generated code, where every line gets a dutiful narration. The comments worth keeping explain what the code cannot: why this approach, why this odd value, what breaks if you change it. The rule: comment the why, not the what. If the comment just translates the code into a sentence, delete it. ## Delete these ```js // increment the counter counter++; // loop over each user for (const user of users) { ... } // return the total return total; // set name to the given name this.name = name; ``` Also delete: - section banners that restate structure: `// Constructor`, `// Getters`, `// Helper functions` - a docstring that only repeats the signature: `/** Gets the user. @param id the id @returns the user */` over `getUser(id)` - commented-out old code left "just in case" (that is what version control is for) - TODOs with no content: `// TODO: fix this` ## Keep these ```js // Stripe rounds half-up; mirror that here so totals reconcile. const cents = Math.round(amount * 100); // The API caps page size at 100; larger values are silently truncated. const pageSize = Math.min(requested, 100); // Intentionally not awaited: fire-and-forget metrics, must not block the response. void reportMetric(event); // Workaround for facebook/react#1234, remove once the fix ships. ``` Keep comments that carr
