javascript - JS regex to split by line

Question

How do you split a long piece of text into separate lines? Why does this return line1 twice?

/^(.*?)$/mg.exec('line1
line2
');

["line1", "line1"]

I turned on the multi-line modifier to make ^ and $ match beginning and end of lines. I also turned on the global modifier to capture all lines.

I wish to use a regex split and not String.split because I'll be dealing with both Linux and Windows line endings.

Answer 1

arrayOfLines = lineString.match(/[^
]+/g);

As Tim said, it is both the entire match and capture. It appears regex.exec(string) returns on finding the first match regardless of global modifier, wheras string.match(regex) is honouring global.
