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>
<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>
You can also import WWWBasic as a Node.js module:
var basic = require('./wwwbasic.js');
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.
