Escape Your Apostrophes in JavaScript

In JavaScript, the apostrophe (') is a string delimiter. That is, it marks the beginning or end of a text string. If you include an apostrophe inside a string, the interpreter spits out an error message such as:

missing ) after argument list. 

You don't need to avoid apostrophes, just "escape" them. The backslash (\) character tells the interpreter not to treat the character as a delimiter. Here's how it looks in code:

<SCRIPT Language=JavaScript>
window.document.write('It ain\'t me babe.')
