I saw this question and I am wondering about the same thing in JavaScript.
If you use the character ' or the character " when making strings in JavaScript, the application seems to behave the same. So what is the difference between these two characters?
The only advantage I have seen in using ' to build strings is that I can do stuff like:
var toAppend = '<div id="myDiv1"></div>';
Instead of:
var toAppend = "<div id=\"myDiv1\"></div>";
Is there any significant difference between them that I should be aware of?

They are equivalent for all intents and purposes. If you want to use either one inside a string, it is a good idea to use the other one to create the string, as you noted. Other than that, it's all the same.
ReplyDeleteThere's no difference. The reason for its existence is exactly what you mentioned
ReplyDeleteYour example is the best example to describe the difference between the two....
ReplyDeleteI think there is another difference. If you do the following
ReplyDeletevar str1 = 'The \' character';
var str2 = 'The " character';
var str3 = "The ' character";
var str4 = "The \" character";
document.write (str1.replace("'","%26");
document.write (str2.replace('"',"%22");
document.write (str3.replace("'","%26");
document.write (str4.replace('"',"%22");
The document.write will fail for str1 and str4. That is the difference, but I don't know if there is a workaround to make them work.
