Source maps map the compiled/transpiled code back to the original source code. When an error occurs in the compiled code, the debugger or stack trace parser can use the source map to pinpoint the corresponding line number in your original TypeScript or ES6+ code. Ensure source maps are generated during the build process and are accessible to the debugger.
