What will happen if sourcemap is set as false in Angular

I'm new in Angular. I saw sourcemap in tsconfig.json and by default it is "sourceMap": true. I had few doubts and found this link useful. Still I have the following doubt regarding the same.

I set "sourceMap": false, but couldn't find any change in the app. What will be the actual change if I set so?
