Returns an object containing the canvas's 2D context and the wrapper's ID. create() - creates a canvas with a specified width and height inside a wrapper with a specified ID, which is itself appended inside a specified parent element.canvas.js - contains functions related to setting up the canvas:.The modules directory's two modules are described below: Note: All of the examples in this guide have basically the same structure the above should start getting pretty familiar. Use of native JavaScript modules is dependent on the import and export statements these are supported in browsers as shown in the compatibility table below. This can only be a good thing - browsers can optimize loading of modules, making it more efficient than having to use a library and do all of that extra client-side processing and extra round trips. The good news is that modern browsers have started to support module functionality natively, and this is what this article is all about. Node.js has had this ability for a long time, and there are a number of JavaScript libraries and frameworks that enable module usage (for example, other CommonJS and AMD-based module systems like RequireJS, and more recently Webpack and Babel). It has therefore made sense in recent years to start thinking about providing mechanisms for splitting JavaScript programs up into separate modules that can be imported when needed. Fast forward a few years and we now have complete applications being run in browsers with a lot of JavaScript, as well as JavaScript being used in other contexts ( Node.js, for example). JavaScript programs started off pretty small - most of its usage in the early days was to do isolated scripting tasks, providing a bit of interactivity to your web pages where needed, so large scripts were generally not needed.
