strip()

I bit more precisely that would be the “strip” method of the “String”
class.

Example:

[1] pry(main)> str = " String with leading and trailing whitespace "
=> " String with leading and trailing whitespace "
[2] pry(main)> str.strip
=> “String with leading and trailing whitespace”

I mention this because “strip” could have a different meaning in other
classes.

Person#strip might have a different meaning entirely. :slight_smile:

One question, I have this follow string

" Hello \n\r How are you ? \n\r I’m fine ."

The strip gonna clean \n\r too ?

Thanks

No, it only acts on the outer bounds of the string. Have a look at the
documentation on ruby-doc.org:
Class: String (Ruby 1.9.3)

strip removes ONLY leading and trailing whitespaces, see:

Basically, PHP’s trim() works the same.

If you want to remove whitespaces inside the string, you need to use
String#gsub or String#squeeze (depending on what you want to
achieve).
