这就从知识的广度上对 Web 前端开发工程师提出了要求。如果要精于前端开发这一行，也许要先精十行。然而，全才总是少有的。所以，对于不太重要的知识，我们只需要”通”即可。但”通”到什么程度才算够用呢?对于很多初级前端开发工程师来说，这个问题是非常令人迷惑的。
This requires web front-end development engineers from the breadth of knowledge. If you want to be good at front-end development, maybe you need to be good at ten lines first. However, all rounders are always rare. Therefore, for less important knowledge, we just need to “connect”. But to what extent is “Tong” sufficient? For many junior front-end development engineers, this problem is very confusing.
Web 发展的很快，甚至可以说这些技术几乎每天都在变化!如果没有快速学习能力，就跟不上 Web 发展的步伐。前端工程师必须不断提升自己，不断学习新技术、新模式;仅仅依靠今天的知识无法适应未来。Web 的明天与今天必将有天壤之别，而前端工程师的工作就是要搞清楚如何通过自己的 Web 应用程序来体现这种翻天覆地的变化。前端开发的入门门槛其实非常低，与服务器端语言先慢后快的学习曲线相比，前端开发的学习曲线是先快后慢。所以，对于从事 IT 工作的人来说，前端开发是个不错的切入点。也正因为如此，前端开发领域有很多自学成”才”的同行，但大多数人都停留在会用的阶段，因为后面的学习曲线越来越陡峭，每前进一步都很难。
The development of web is very fast, even these technologies are changing almost every day! Without the ability of fast learning, we can’t keep up with the development of web. Front end engineers must constantly improve themselves and learn new technologies and models; they cannot adapt to the future only relying on today’s knowledge. The future of the web is bound to be very different from today’s, and the job of front-end engineers is to figure out how to reflect this earth shaking change through their own web applications. The entry threshold of front-end development is actually very low. Compared with the learning curve of slow first and then fast, the learning curve of front-end development is fast first and then slow. Therefore, front-end development is a good starting point for people engaged in it work. Because of this, there are many self-taught “talent” peers in the front-end development field, but most people stay at the stage of using, because the learning curve behind is getting steeper and steeper, and it is difficult to further each time.
