10.1.1 String literals

A string literal is a sequence of characters inside a pair of double quotes or single quotes:

var a = "foo";
var b = 'foo';
trace(a == b); // true

The only difference between the two forms is that single-quoted literals allow string interpolation.

String literals may occupy multiple lines; In which case, each line of the string will be punctuated with a '\n' newline character (See the escape sequences chart below).

var str = "Line one
Line two
Line three";
trace(str);

Note that indentation will also be included in the string, such as with the example below.

class X {
  function foo() {
    var str = "a
    b
    c";
  }
}

The str variable will have four spaces before 'b' and 'c'.
