Devin issues we find in JavaScript projects
Problems specific to Devin's code generation patterns when building JavaScript apps.
Autonomous security decisions
Devin makes security-related decisions without human review — choosing auth strategies, setting permissions, and configuring access controls that may be inadequate.
Compounding architectural errors
When Devin makes an early architectural mistake, it builds subsequent features on top of it. By the time you notice, the issue is deeply embedded in the codebase.
Workarounds instead of fixes
When Devin encounters an error, it sometimes adds workarounds that mask the root cause rather than fixing the underlying issue.
Inefficient retry patterns
Devin's debugging approach sometimes results in retry logic and fallback patterns that hide errors rather than resolving them, impacting performance.
JavaScript issues we check for
Common JavaScript problems that affect production readiness.
Prototype pollution
AI-generated code merges user-supplied objects into prototypes via Object.assign or spread operators without sanitization, enabling property injection attacks.
Loose equality comparisons
Using == instead of === leads to type coercion bugs where '0' == false, null == undefined, and other non-obvious truthy/falsy comparisons cause silent logic errors.
Unhandled promise rejections
Async functions without try/catch or .catch() handlers cause unhandled rejection warnings and silent failures in production.
Global variable leaks
Missing 'const' or 'let' declarations create implicit globals that pollute the global scope and cause unpredictable behavior across modules.

Frequently asked questions
Can you review JavaScript code generated by Devin?
Yes. We regularly audit JavaScript projects built with Devin and understand the specific patterns and issues it introduces. Our review covers security, performance, and deployment readiness.
What JavaScript issues does Devin typically create?
Common issues in Devin-generated JavaScript code include: autonomous security decisions, compounding architectural errors, workarounds instead of fixes. Combined with JavaScript-specific concerns like prototype pollution and loose equality comparisons.
How do I make my Devin JavaScript project production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Devin-built JavaScript projects, the typical path is: fix security gaps, address JavaScript-specific performance issues, then configure deployment. We provide a fixed quote after the audit.
