Assign Name to Loop

Question

//Set the number of spaces in front of text
numSpaces = 20;
//
spaces = "&nbsp";
//
importantMessage = "This is a variable message that I will define";

for (var i = 0; i < numSpaces; i++)
{
//here is the output on screen
document.write(spaces)
}

//printing the full message
document.write(importantMessage);

I'm currently teaching myself javascript. I'm so confused if this is breaking a law in JS land, but how do I define a loop with a name? I would like to give the whole section from for (var...to write(spaces)} a name, so then I can do document.write(nameofloop + importantMessage) which of course will print out what I need. When I do define a name, somehow the loop says "undefined" before the "important message."

Unless there is a better way to loop some html code that is user defined. I want to be able to make a number of spaces before the message on my crawler message and it could vary depending on the user.

I'm confused on multiple { { } } as I will eventually make an if statement once I get this working. Thanks!

It's not really clear what you want to do. Can you post some pseudo code for what you are trying to accomplish? Also, what should document.write(nameofloop + importantMessage) print out? — Chris Laplante

@SimpleCoder nameofloop is what I am trying to define a loop. Currently, if I use the code as the poster below, I still get an undefined before the first word. "document.write(writeSpaces(10) + importantMessage)" is what I am using. — traveler84

If you're wanting to "name" chunks of code for use, you're probably under-using functions. The best approach is to wrap the loop into a function:

function writeSpaces(numSpaces) {
    for (var i = 0; i < numSpaces; i++) {
        document.write(spaces);
    }
}

Then call it like

writeSpaces(10);
