但总之.它不会取代 javascript.

But in short. It does not replace javascript.

HTML 5 canvas 为您提供了一个简单且强大的方法来绘制图形使用JavaScript.对于每个画布元素你可以使用上下文"(想想一个绘图板中的页面)，您可以在其中可以发出 JavaScript 命令来绘制任何你想要的.浏览器可以实现多个画布上下文和不同的 API 提供绘图功能.

HTML 5 canvas gives you an easy and powerful way to draw graphics using JavaScript. For each canvas element you can use a "context" (think about a page in a drawing pad), into which you can issue JavaScript commands to draw anything you want. Browsers can implement multiple canvas contexts and the different APIs provide the drawing functionality.
