Strings are immutable and do not support any operation (e.g. concatenation). Like comments, strings can span across multiple lines. Whitespace (i.e. newlines, tabs, spaces) is part of the string. Escape sequences are not supported. ( AKA escape sequences are not interpreted as special, but rather just as normal characters...
) -> "escape" escape sequences, i.e. format print the string into a new string (val = format!("{}", val);
