What is the difference between ‘ and ” in JavaScript?

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?

Answer

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.
