Step-by-Step Solution

Solution:

Step 1: Understand how to represent multiple errors
Using an array of error objects allows clear, structured multiple errors.
Step 2: Evaluate JSON structures for clarity and machine readability
{"errors": [{"code": "E001", "message": "Invalid email"}, {"code": "E002", "message": "Password too short"}]} uses an "errors" array with separate code and message for each error, ideal for machines.
