In actionscript, some code goes like this: trace();. So in trace statements I can both use an apostrophe or quotes. So is there any difference if I'm using each one? Example: difference between trace("Works!"); and trace('Works!');. Is there any reason why each works and not just one?

  • @Abe "actionscript quote reference" or "actionscript quote syntax" might be better search phrases - same with operators and such; best resource for syntax is usually the authoritative reference or a companion guide. – user2246674 Apr 28 '13 at 20:20

The only difference is the quote token and required escaping of such. (That is, unlike some languages, there are no special rules between the two forms.)

The AS3 developer guide Creating Strings article discussed when using one quote over the other is preferable - it all comes down to when the particular quote needs to be escaped.

You may choose to use single quotation marks or double quotation marks based on any single or double quotation marks that exist in a string literal, as in the following:

var str1:String = "ActionScript <span class='heavy'>3.0</span>";

var str2:String = '<item id="155">banana</item>';
