Kid.js is a framework designed to make JavaScript more accessible for kids and beginner programmers. It eliminates the need to first understand the DOM and provides functions to create drawings, animations and simple games.

Why Learn JavaScript?

JavaScript is the most popular programming language, and growing. It was created to power interactive websites, but has since grown beyond the web browser and is used to write applications large and small, on servers and on mobile devices.

JavaScript shares a similar syntax with many other programming languages such as C/C++, Swift, Java and Kotlin, but is a little more forgiving. It can be a great jumping off point to other more structured languages.

Getting Started

Use the following HTML template to get started. Any code written inside of <script type="kidjs"> tags will be executed by the framework.

<html> <head> <title>Kid.js Example</title> <script src="https://cdn.jsdelivr.net/npm/@maissaninc/kidjs/dist/kid.min.js"></script> </head> <body> <script type="kidjs"> write('Hello World'); </script> </body> </html>

The Stage

The shape functions in Kid.js create new objects which are added to the stage.

star(400, 200, 250)

Each object has a set of properties that can be modified, such as fill color, stroke color, line width, etc.

let sirius = star(400, 200, 250) sirius.fill = 'gold' sirius.stroke = 'orange' sirius.lineWidth = 10

In addition to their properties, most objects also have a set of functions or methods that can be executed.

let sirius = star(400, 200, 250) sirius.spin()
