Ruby: Delete space after every comma?
What would be the ruby code to delete whitespace after every comma in a string? I'm not sure why this didn't work..
.gsub(/[, ]/, ',')

"hello, world".gsub(/, /, ',')
The [] are used to match any of the contained characters. You are replacing every comma or space with a comma.
