How do I avoid trailing empty items being removed when splitting strings?

by

There’s a limit parameter to .split(pattern=$;, [limit]). If limit is omitted, trailing null fields are suppressed. You need to provide a negative limit

"b::::c:::".split(':', -1)

but bear in mind that this will return three "" values at the end of the array.

result: ["b", "", "", "", "c", "", "", ""]
