RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including TPA. Try it out:
var Tpa=require('TPA');
// Create 3 new Tpa numbers
var n1=new Tpa('123 43/57');
var n2=new Tpa('-5.57[13]');
var n3=new Tpa(12.6);
// Multiply them together into a new Tpa starting at 1
var product=Tpa(1,false); // 'false' means NOT an integer - i.e. can hold fractional part
product.multiply(n1).multiply(n2).multiply(n3).simplify();
// et voila...
'['+n1.toFraction()+'] * ['+n2.toFraction()+'] * ['+n3.toFraction()+'] equals ['+product.toFraction()+'] ('+product.toDecimal()+')';

require()any package directly from npm- use arrow functions, classes, template strings, and most of ES6
awaitany promise instead of using callbacks (example)- create your own embedded node.js snippets
