You won't see a difference for this specific example since the split function
supports character, string and even range separators. So, use what works best
for your use case.
But here's the difference between them:
Single quotes are for singular characters, 'hello' won't compile while ';' and
'\n' (escaped newline) will.
Double quotes are string literals, i.e. array of characters, which also allow escape
sequences like "\r\n".
Back ticks, as well as r"...", are raw or wysiwyg ("what you see is what you
get") strings, they do not support escape sequences. They are super useful for regex.
import std;
void main() {
writeln("ab\ncd"); // \n is recognized as a newline character
writeln(`ab\ncd`); // `...` and r"..." are equivalent
writeln(r"ab\ncd");
}
will print:
ab
cd
ab\ncd
ab\ncd
