I need a tokenizer that given a string with arbitrary white-space among words will create an array of words without empty sub-strings.

For example, given a string:

" I dont know what you mean by glory Alice said."

I use:

str2.split(" ")

This also returns empty sub-strings:

["", "I", "dont", "know", "what", "you", "mean", "by", "glory", "", "Alice", "said."]

You probably don't even need to filter, just split using this Regular Expression:

"   I dont know what you mean by glory Alice said.".split(/\b\s+/)
