Difference between write() and writeln()

writeln() adds a newline character after each statement. write() does not.

Example

document.write("Hello World!");
document.write("Have a nice day!");
document.write("<br>");
document.writeln("Hello World!");
document.writeln("Have a nice day!");

Try it yourself

Note

Use in HTML writeln() is meaningless. It is only useful when writing a text document (type=".txt"). Newline characters are ignored in HTML.

If you want to break lines in HTML, you must useParagraphOr <br>：

Example 1

document.write("Hello World!");
document.write("<br>");
document.write("Have a nice day!");

Try it yourself

Example 2

document.write("<p>Hello World!</p>");
document.write("<p>Have a nice day!</p>");
