Task definitions for the Code Review environment.
3 tasks with progressive difficulty: easy → medium → hard
Each task covers a distinct bug category: syntax, logic, performance.

"This function has a syntax error in its parameter list. "

"category": "performance",
"title": "Inefficient Array Iteration",

"This loop re-evaluates arr.length on every iteration and uses verbose "
"index-based access. A modern functional approach is cleaner and avoids "
"repeated property lookups."
