Answer 1

You can do the following:

1. Replace all non-word characters by a white space:

   str = str.replace(/[\W\d\s]+/g, ' ');
   

   You might have to adjust this to your needs, to replace the right characters:

   • \W matches everything expect letters, digits, and underscores
   • \d matches digits
   • \s matches white spaces

   There are other ways to write an equivalent expression.

2. Then split bye white space:

   words = str.split(' ');
   

Regular-Expressions.info is a good website to learn about regular expressions. For regular expressions in JavaScript, have a look at the MDC documentation.
