If that string is specified as a literal, then the code must be written as a quote itself (and escaped accordingly).
For example: This code declares a variable a, which is assigned the value 3, and a blank alert window is popped up to the user.
[2] For example: Furthermore, (unlike in the literature example), the third-level nested quote must be escaped in order not to conflict with either the first- or second-level quote delimiters.
Here are some examples that demonstrate some of the above principles: Note that the number of backslashes increase from 0 to 1 to 3 to 7 to 15, indicating a
rule for successively nested symbols, meaning that the length of the escape sequences grows exponentially with quotation depth.
