We would here review in brief about them and the modus operani adopted therein.
- Simple parsing using regular expressions to remove comments
- Newlines are removed and hence the entire function now occupies a single line when done a ViewSource.
- Unnecessary Whitespaces are removed.
There are a few caveats using the crunchers. Since newlines are removed, scripts if they are not properly delimited by semicolon might break. Hence take a backup of those scripts before running a cruncher on them.
