We all know that the front water is very deep, the big pit.
Because she has a wide range of knowledge, the farther back, the wider or deeper.
Relative to the back end of the first slow after fast, the front end is fast after slow, easy to learn difficult to fine
Select the front end, of course, because I have the same level of algorithm.
Feel free to search "how to become a good front-end development engineer", you can find the front-end to learn something is immeasurable
It is also because of this, I like the challenge, challenges all kinds of knowledge, and here all kinds of knowledge, are linked to the front of the road.
The personal expectation is that it will take about 5-10 years to understand most of the knowledge of the front-end, and, of course, there is a chance to invest and focus more on the details in the future.
Mark: This is just the idea of the moment, and I don't know what I would think about a few years later.
Why do I have to pick the front line?
