Ruby: Convert a string to an array of characters

"This is the bee's knees".scan /\w/
#=> ["T", "h", "i", "s", "i", "s", "t", "h", "e", "b", "e", "e", "s", "k", "n", "e", "e", "s"]

String's #scan will look for anything matching your pattern and return it in an array.

You can also do "test".split("")

That would include spaces, the scan only returns what matches the regex. Nice find!

Thank You. I used .scan instead of .split to make a small improvement in this 'Rubymonk module' lesson (second code from the bottom of the page)

"This is the bee's knees".chars will do the job

"This is the bee's knees".chars also includes spaces. Using #scan does not include them.

Thank you this was helpful - I actually needed the spaces so thanks @maycry for the .chars tip

"This is the bee's knees".tr(" ' ", "").split.join('').split('') # All chars that may need to be removed from string may be placed in 1st parm of #String.tr method
