Quick Reference
The document.writeln() method writes directly to an open HTML document, with the addition of writing a newline character after each statement.
// write to the document
document.writeln('Hello World!');
document.writeln('Have a wonderful day.');
document.writeln('<p>And have a great week!</p>');Note
The writeln() method deletes all existing HTML when used on a loaded document, and cannot be used in an XHTML or XML document.
Output
Hello World!
Hava a wonderful day.
And have a great week!Note
The writeln() method automatically adds a new line after each statement.
Syntax
document.writeln(text or html)JavaScript Notes:
- When using JavaScript, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- JavaScript is a case-sensitive language; firstName is NOT the same as firstname
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
- JavaScript variables must begin with a letter, $, or _
- JavaScript variables are case sensitive (x is not the same as X)
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
