Expert code review for JavaScript apps built with Tabnine. We find Tabnine-specific bugs, fix JavaScript security issues, and optimize performance. From $19.
Tabnine issues we find in JavaScript projects
Problems specific to Tabnine's code generation patterns when building JavaScript apps.
Perpetuating existing security flaws
Because Tabnine learns from your codebase, it replicates existing security anti-patterns. If your code has XSS vulnerabilities, Tabnine suggests more of them.
Copying insecure patterns from teammates
Tabnine learns from the entire team's code. One developer's insecure patterns get suggested to everyone, spreading bad practices across the codebase.
Subtle copy-paste errors
Tabnine suggests code similar to existing code, but with small differences that cause bugs — wrong variable names, incorrect conditions, or missing parameters.
Stale patterns from old code
Tabnine suggests patterns from older parts of the codebase, even if the team has since adopted better practices.
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.
