Not able to practice debugging lesson because javascript code is not on separate lines

[jai-sanghvi]

I've noticed 2 issues while going through the "Debugging in the browser" chapter.

1. The "hello.js" file on this example page has the 2 functions written in just 1 line and so it's not possible to add a breakpoint at places within the function as instructed in the chapter.
2. Also, there's no "enable/disable automatic pause in case of an error." button on either chrome or edge as said in the chapter.
