A broader definition comes from the organization that Web inventor Tim Berners-Lee helped found, the World Wide Web Consortium (W3C). The World Wide Web is the universe of network-accessible information, an embodiment of human knowledge.
In simple terms, The World Wide Web is a way of exchanging information between computers on the Internet, tying them together into a vast collection of interactive multimedia resources.

11.  Explain functions in Javascript with syntax and example.

JavaScript functions are defined with the function keyword. You can use a function declaration or a function expression. Earlier in this tutorial, you learned that functions are declared with the following syntax:

function functionName(parameters) {
 
// code to be executed
}
Declared functions are not executed immediately. They are "saved for later use", and will be executed later, when they are invoked (called upon).
function myFunction(a, b) {
 
return a * b;
}

12.  Which are the different popup boxes in Javascript? Explain each with syntax, example and its significance.
JavaScript has three kind of popup boxes: Alert box, Confirm box, and Prompt box.

Alert Box

An alert box is often used if you want to make sure information comes through to the user.
When an alert box pops up, the user will have to click "OK" to proceed.

Syntax

window.alert("sometext");

Confirm Box

A confirm box is often used if you want the user to verify or accept something.
When a confirm box pops up, the user will have to click either "OK" or "Cancel" to proceed.
If the user clicks "OK", the box returns true. If the user clicks "Cancel", the box returns false.

Syntax

window.confirm("sometext");

Prompt Box

A prompt box is often used if you want the user to input a value before entering a page.
When a prompt box pops up, the user will have to click either "OK" or "Cancel" to proceed after entering an input value.
If the user clicks "OK" the box returns the input value. If the user clicks "Cancel" the box returns null.

Syntax

window.prompt("sometext","defaultText");
