整体在进入正式的render流程之前,React Fiber本身其实做了大量工作,从入口处更能理清整个挂载更新过程的主体脉络: image-20220915202823214 在有了这个脉络之后,我们就可以把重点放在三个方向上: beginWork具体做了什么事情?(实际上它很重要,整个reconciler都是这个阶段完成) completeWork具体做了什么事情? commit具体做了什...

在使用React进行构建应用时,我们总会有一个步骤将组建或者虚拟DOM元素渲染到真实的DOM上,将任务交给浏览器,进而进行layout和paint等步骤,这个函数就是React.render()。首先看下该函数的接口定义: ReactComponent render( ReactElement element, DOMElement container, [function callback] ) ...
下面是,我们在React-官网中实验的结果。 从输出结果来看,虽然结果不是唯一,但是它们的值都稳定在16.67~16.68。和我们60fps是吻合的。 WebAPI WebAPI工作的原理依赖于浏览器作为宿主环境来提供和执行这些API。在Web开发中,我们通常指的WebAPI是「浏览器内置的API」,它们允许开发者利用JavaScript与浏览器的功能进行交互。
