Choosing the right tool
How is this different from the TypeScript Code Checker?
The TypeScript Code Checker is diagnostic-first: it gives you a list of issues to work through, with corrected code as a secondary section. The Code Fixer is solution-first: it leads with the complete working code, shown as a diff against your original, and briefly explains what changed. Use the TypeScript Code Checker when you want a fuller issue-by-issue review.
Common questions
Frequently Asked Questions
How do I fix broken TypeScript code using CodeConvert AI?
Paste your broken or non-working TypeScript code into the input box, optionally add the error message or traceback you're seeing, and click Fix Code. Our AI will diagnose the problem and return the complete, corrected TypeScript code along with a summary of what changed.
What kinds of TypeScript problems can this tool fix?
This tool can fix a wide range of problems in TypeScript code, including syntax errors, logic errors, off-by-one bugs, null/undefined access, type mismatches, and the specific error or exception in a traceback you paste in.
Should I include the error message when fixing TypeScript code?
It's optional, but recommended. If you have an error message or traceback from running the TypeScript code, pasting it into the "Error message / traceback" box helps the AI pinpoint the exact cause instead of guessing, which usually produces a more accurate fix.
