Refactor Code for your JavaScript project
Expert refactor code for JavaScript applications. We find and fix JavaScript-specific bugs and security issues that affect production apps. From $19.
JavaScript refactor code issues we find
Common refactor code problems specific to JavaScript applications.
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.
eval() and dynamic code execution
AI tools sometimes use eval(), new Function(), or setTimeout with strings to handle dynamic logic, opening severe code injection vulnerabilities.
What our JavaScript refactor code covers
Component restructuring
Breaking down god components into focused, reusable pieces with clear responsibilities.
Code deduplication
Identifying and consolidating repeated logic into shared utilities and hooks.
Architecture improvement
Separating concerns — UI from business logic, data fetching from rendering, config from code.
Type safety
Adding or improving TypeScript types to catch bugs at compile time instead of runtime.
Error handling patterns
Implementing consistent error handling, logging, and user-facing error messages throughout the app.
Dependency cleanup
Removing unused packages, updating outdated dependencies, and consolidating redundant libraries.
