How do I create a new line in Javascript?

Question

var i;
for(i=10; i>=0; i= i-1){
   var s;
   for(s=0; s<i; s = s+1){
    document.write("*");
   }
   //i want this to print a new line
   /document.write(?);

}

I am printing a pyramid of stars, I can't get the new line to print.

Answer 1

Use the \n for a newline character.

document.write("\n");

You can also have more than one:

document.write("\n\n\n"); // 3 new lines!  My oh my!

However, if this is rendering to HTML, you will want to use the HTML tag for a newline:

document.write("<br>");

The string Hello\n\nTest in your source will look like this:

Hello!

Test

The string Hello<br><br>Test will look like this in HTML source:

Hello<br><br>Test

The HTML one will render as line breaks for the person viewing the page, the \n just drops the text to the next line in the source (if it's on an HTML page).

Answer 2

For a string I just write "\n" to give me a new line. For example, typing console.log("First Name: Rex" + "\n" + "Last Name: Blythe"); Will type:

First Name: Rex

Last Name: Blythe

Answer 3

Use a <br> tag to create a line break in the document

document.write("<br>");

Answer 4

\n dosen't work. Use html tags

document.write("<br>");
document.write("?");

Answer 5

If you are using a JavaScript file (.js) then use document.write("\n");. If you are in a html file (.html or . htm) then use document.write("<br/>");.

Answer 6

Alternatively, write to an element with the CSS white-space: pre and use \n for newline character.
