If I have a one liner method that looks like this:str.toLowerCase.replaceAll([^\\w'],  ).split( ).filter(word => word.trim.length >= 1).groupBy(word => word).mapValues(_.size)What is the best way to avoid long lines of code and split it into multiple lines? Here are the options that I see:Assign part of the methods chain to a val and start from line 2 with val.(rest of method chain)Move some parts to own methods with meaningful names (onlyChars, trimmedText, ...)Just split the lines and make the second line nested in the first one
How to split long lines of code?
