I'd like to take a textarea's worth of people's names, entered by a user, and separate them into items in an array.
Take a theoretically possible input:
people = "Abby Andrews, Ben \r\nCharlie Connors Daphne D., Ernie E. Engels; Faye\r\n\r\nGary Gomez"
array = people.split('??')
How can the regex be constructed to successfully split a crazy chain like the above?
Should be split:
\r, \n, \r\n
,) or semi-colon (;)Should not be split:
I tried people.split(/\r\n,;/), people.split(/,;\r\n/), and combinations thereof but none produced the result.

Thus, if you use a semicolon (;) in a keyword expression, it will split the keywords into multiple parts. Semicolon is not in RegEx standard escape characters. It can be used normally in regular expressions, but it has a different function in HES so it cannot be used in expressions.
To split a string by newline, call the split() method passing it the following regular expression as parameter - /\r?\ n/ . The split method will split the string on each occurrence of a newline character and return an array containing the substrings.
The 0-9 indicates characters 0 through 9, the comma , indicates comma, and the semicolon indicates a ; . The closing ] indicates the end of the character set. The plus + indicates that one or more of the "previous item" must be present.
Try
array = people.split(
/\s*[,;]\s* # comma or semicolon, optionally surrounded by whitespace
| # or
\s{2,} # two or more whitespace characters
| # or
[\r\n]+ # any number of newline characters
/x)
