How can I get the array

[“hello”, “world”, “123”]

from the string

“hello\r\nworld\r\n123”

Thanks!

Thanks! (I like your book BTW - I like how it touches on main, Kernel  
stuff, etc…)

I was trying “hello\r\n\world”.split(’\r\n’) and it returned  
[“hello\r\nworld”]

You need to use a double quoted string in order for those escaped  
characters to be interpereted as such.
