HUMILIATION
Can you give us an eli5 on sourcemaps?
Usually when code is minified, it is shipped alongside a sourcemap (*.js.map), which can be used by the browser to show you the original code.
If you get an error in the browser, you can click the error, which will take you to the network(?) tab and show you exactly where the error occurred
Also when code has been compiled, or transpiled. The reason the line numbers don't match is because all of the code is being assembled into one large package and served to whatever client uses it. So even if you don't minify, but you're compiling, sourcemaps will show you where the error actually occurs, instead of where it occurs in the finished product.
Especially if the compiler optimization options inlined code from 5 different places into one blob
