Difference: "Hello, world" is a string to show in alert box. Helloworld is assumed as variable by JS, but you didn't declare it, there's no variable by the name Helloworld, that's why it didn't work.

Variables are temporary storage for values, variables can contain string, numbers, and many more types of values. Your last question: var a = 2; Declare a variable named a, and assign a numeric value 2 into it. You can later on use the content of the variable by referring to its name. alert("value of a is : " + a); [Note] @Metaaa, if you're interested in this I suggest you join the HTML, CSS, and JavaScript course, it's fun! go and give it a try!

Then you have good reason to join the course, by joining the course you learn, by learning, you will understand, I see you joined Java course already, but if you want to make web page you start with HTML, then move on to CSS, and finally, JavaScript. Good luck. Hth, cmiiw

@Metaaa your frames code was incorrect, you can't mix rows and cols specification on a <frameset>. Furthermore, frames are deprecated (no longer supported) by HTML 5 standard. I still don't see you in HTML class, you can learn how to design your HTML page without frames in there. Here's a reading about HTML frames, look it up, just for reference: https://www.tutorialspoint.com/html/html_frames.htm Hth, cmiiw
