Point them toward linters (like ESLint) or formatters (like Prettier). Use Visuals:
Run the new code. Test edge cases: empty table, database lock errors, concurrent calls. idea correct the problematic code answers
: Syntax errors are trivial (missing semicolons), but semantic errors (incorrect algorithm implementation) require deep domain knowledge. Edge Case Sensitivity : Problematic code often works for but fails for or very large datasets. Point them toward linters (like ESLint) or formatters
Correcting problematic code is one of the most accurate ways to simulate . It moves beyond "Can you write a loop?" to "Can you find why this loop fails under stress?". For teams hiring for senior roles or site reliability, this format is superior to standard "whiteboard" coding. database lock errors
