Javascript-how should front-end engineers learn backend knowledge?

For example, I plan to learn nodejs at present, and the level is css. there is no problem with all kinds of front-end frameworks of jquery. native js is not very skilled. I have never touched on database issues, and I don't know how to start with it. what mongodb and express have stunned me.

First, you need to clarify your development direction. if it is to attack the backend, you can start with java and mysql, which is the most basic. if it is the front end, you can read the native javascript again, I tried to write something. now there are many front-end js-based frameworks, such as vue. js, react. js and so on. I learned to be proficient in one course, and the later frameworks are handy. if you don't have any backend Foundation, we suggest you do a good job of front-end. now the front-end is also delicious!

Learning from the installation environment, then learning the back-end syntax, first learning how to create a page, and the most basic function operations, then the database connection, writing SQL statements, in this way, you can get started.

Easy to move, your best choice: git.oschina.net/sectong

If you do not learn js well in one day, you cannot become a front-end engineer in one day.

You can certainly complete some simple tasks based on your acquired experience, but the progress is slow enough.

I suggest you study JS. do not think too much.

Don't think too far away.

Learn the core part of js. Look at other people's code.

Backend knowledge, which may be exposed later or later.

When your js is ready, go to nodejs again.

Honestly, it is not recommended to look at the specific implementation at the beginning. if you are a front-end JavaScript, you must be familiar with it. you just need to learn nodejs at the backend, find a framework express or koa and try to output a page that you usually write. First, make a small achievement and then learn the knowledge behind the problem, in the first place, it was easy to get rid of your patience to look at the things behind your back-end. As for the database and cache, it would be much easier if you have basic backend knowledge, the phone code word may be incorrect. it is for reference only.

Js is actually passed, and then node. js will be difficult.

Js must be better. this is the foundation of the front-end. after all, node. js is written by js. learning Node. js is the basic thing that uses a lot of js resources. I am still optimistic about js learning Node. js.

I still cannot learn the front-end yet. I want to learn JS well first. I also tried to learn nodeJS, but I have a lot of backend knowledge and I don't know much about http. I have to put it down first. I am now studying PHP by myself,
