[TW5] Why are double quotes preferred over single quotes for string literals?

[andrew harrison]

Why are double quotes preferred over single quotes for string literals? It means that every time there is a double quote character it takes up twice the space in the core or in plugins because it has to be escaped. Single quotes don't have to be escaped so why not use those whenever possible? I'm just asking because I'm finding it reduces size, increases speed and the only exception I can find to using single over double is triple.

It's just a convention, which is probably active since TWclassic, and discussing it may cause a "religious war" ;)

It's exactly the same problem and argument with 'I don\'t want to escape double quotes'. If I do understand your argument right.

See my example above. also see: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String

I don't understand this statement. ... I think nobody (except the browser programmers) really know, what browsers do with our strings. So trying to optimize speed and memory usage with using ' over " is wasting time.

just some thoughts

Ok, I am now seeing the rediculousness of my question. It would require way to much work to replace double with single and for what reason and is a waste of time. Not a good idea to mess with a work of art. Thank you for your valuable guidance.

Hi Andrew

Why are double quotes preferred over single quotes for string literals? It means that every time there is a double quote character it takes up twice the space in the core or in plugins because it has to be escaped. Single quotes don't have to be escaped so why not use those whenever possible? I'm just asking because I'm finding it reduces size, increases speed and the only exception I can find to using single over double is triple.

Just to answer the “why”: I’ve always defaulted to using double quotes for string literals in code because I find that single quotes appear in literal strings much more often than double quotes (mainly because of the way we re-use the single quote as an apostrophe).

Best wishes
