String.trim([filterStr])
String.trim()
String.trim
The .trim operator removes unwanted characters from the start and end of a string. With no arguments, .trim() removes whitespace and end of line characters.
"Hello world ".trim; → "Hello world"
It may also be used with a literal string argument filterStr. The only accepted value for filterStr is "punctuation", in which case the operator also removes punctuation marks.
"[tab] Hello world?! ".trim("punctuation") → "Hello world"
The resulting string retains any stying in the source string.
