" summary

Explains how a generated Source map lets the browser show original TypeScript file lines and accept breakpoints even though it runs compiled JS; build tools produce a separate .map file that points the runtime error back to main.js origins, so devtools step into and debug the TypeScript code instead of the emitted bundle, demonstrating that source maps map runtime locations back to original sources and actually enable line-accurate debugging.
