WPL Get Started Ported To JavaScript

node v0.12.18

version: 6.0.0

This is a JavaScript translation of the first lesson from Wolfram Programming Lab found here: https://lab.open.wolframcloud.com/objects/wpl/GetStarted.nb One of the nice things is that all the APIs we'll use are completely open, so if you want to dig deeper, you can actually drill in and find out how they're implemented (and even fork them!). This will be useful for the more complex examples further down like the image manipulation with filters.

Add 2 and 2.

2+2

A list of numbers from 1 to 10.

require("ramda").range(1, 11)

Draw a circle using the canvas API.

var canvas = new (require("canvas"))(200, 200); var context = canvas.getContext("2d"); context.arc(100, 100, 100, 0, 2 * Math.PI, false); context.fill(); canvas.toBuffer()

Find an image of a horse using Google. If you want to learn about how this API works, just go to https://tonicdev.com/tolmasky/google-image-search

var notebook = require("notebook"); var googleSearch = notebook("tolmasky/google-image-search/3.0.0"); var horseImage = await googleSearch("horse (domestic)");

Apply an oil painting effect. Interested to know how this filter works? Just go to https://tonicdev.com/tolmasky/oil-paint-filter to see how it was implemented.

var oilPaint = notebook("tolmasky/oil-paint-filter/7.0.0"); oilPaint(horseImage);
