以React超级加速渲染大型列表

Rendering large lists in React can be a challenging task for developers. As the size of the list grows, the DOM (Document Object Model) tree also grows, leading to performance issues like slow rendering, janky scrolling, and high memory usage. In this article, we will discuss some of the common problems that developers face while rendering large lists, and various solutions that can be used to overcome them.

在React中渲染大型列表对开发人员来说是一项具有挑战性的任务。随着列表的大小增长，DOM（文档对象模型）树也会增长，导致性能问题，如渲染缓慢、滚动卡顿和内存使用过高。在本文中，我们将讨论开发人员在渲染大型列表时面临的一些常见问题，以及可以用来克服这些问题的各种解决方案。

Why is rendering a massive list in a web browser a challenging task? Well, there are a few factors to consider while rendering a massive list of items. Firstly it’s the performance, as the number of elements to render on the screen increases, the browser’s rendering engine starts hitting performance issues. This would lead to slow rendering, resulting in a sluggish user interface and poor user experience.

为什么在Web浏览器中渲染大型列表是一项具有挑战性的任务？嗯，渲染大型项目列表时需要考虑一些因素。首先是性能，随着要在屏幕上渲染的元素数量增加，浏览器的渲染引擎开始出现性能问题。这将导致渲染缓慢，从而导致用户界面迟缓和用户体验差。

Manipulating a massive list of elements will be computationally expensive. Scrolling through a large list can be janky for your end users, and in the worst cases, they could end up with a completely unresponsive page. The negative impact on low-end devices like mobile phones would be even greater due to limited processing power and memory.

操作大型元素列表将消耗大量计算资源。在大型列表中滚动可能会对最终用户产生卡顿的效果，而在最糟糕的情况下，他们可能会遇到完全无响应的页面。对于移动电话等低端设备的负面影响将更大，因为其处理能力和内存有限。

With all these issues considered, we as software developers need to employ optimization techniques and choose appropriate strategies.

考虑到所有这些问题，作为软件开发人员，我们需要采用优化技术并选择适当的策略。

This article revolves around rendering massive lists in React. Firstly we’ll define what we mean by a massive list. Then we’ll look into some possible solutions you can incorporate to solve the issues pointed out in the problem statement. Finally, we’ll jump into a few key things to keep in mind while rendering a massive list in browsers.
