Comment Guidelines

• Use comments sparingly
• Don't comment out code
  • Remove it instead
• Don't add comments that describe the process of changing code
  • Comments should not include past tense verbs like added, removed, or changed
  • Example: this.timeout(10_000); // Increase timeout for API calls
  • This is bad because a reader doesn't know what the timeout was increased from, and doesn't care about the old behavior
• Don't add comments that emphasize different versions of the code, like "this code now handles"
• Do not use end-of-line comments
  • Place comments above the code they describe
