WWWBasic is an implementation of BASIC (Beginner's All-purpose Symbolic Instruction Code) designed to be easy to run on the Web.
You can include WWWBasic directly in Web pages:
<!DOCTYPE html>
<html>
<head>
<script src="https://google.github.io/wwwbasic/wwwbasic.js"></script>
<script type="text/basic">
PRINT "Hello World!"
FOR i = 1 to 10
PRINT "Counting "; i
NEXT i
</script>
</head>
</html>You can also import WWWBasic as a Node.js module.
Either install it via npm: npm install -S wwwbasic
or clone the repository: git clone https://github.com/google/wwwbasic.git
Then run your code:
var basic = require('wwwbasic'); // from NPM
// var basic = require('./wwwbasic.js'); // from within the cloned repository directory
basic.Basic(
`
PRINT "Hello World!"
FOR i = 1 to 10
PRINT "Counting "; i
NEXT i
`);It supports a range of features including:
- Graphics: 24-bit color, PSET, LINE, CIRCLE.
