A list of items that are good to consider when making any changes.

Code

• My code is as flat as possible (avoids deeply nested if/else blocks, promise chains, etc)
• My code changes account for null/undefined values and handle errors appropriately
• My code uses types/interfaces to help describe values/parameters/etc, help ensure type safety, and improve readability
