What is the difference between using single and double quotes in js. Which should I use for writing concatenated strings
I was taught to write strings "like this" but I see the instructor in the videos writing things like( '<h1>You guessed the number!</h1>'); Is there a difference between the using the single and double quotes and what is it?

var stringOne = 'It\'s a girl!'; var stringTwo = "It's a girl!"; var stringThree = 'He said, "I don\'t want to."'; var stringFour = "He said,\"I don't want to.\"";
Things can also get hairy when using regular expressions.
My personal preference is to just stick to one, and use the other when you have to.
There is no preferred method, either single or double quotes are OK.. You can use either. However if you are using one form of quote in the string, its a good idea use the other as the literal.
alert('Say Hello'); // Say Hello alert("Say Hello"); // Say Hello alert('Say "Hello"'); // Say "Hello" alert("Say 'Hello'"); // Say 'Hello'
