Let's talk about web front end [Copy link]

 

I have worked in MCU development for several years, doing schematics, drawing boards, writing programs, device selection, testing, etc. The work was trivial and the knowledge content was not high. I felt tired and turned to being a programmer. But I still warn everyone not to change careers easily. It is not easy to find a job without relevant work experience. Changing careers means starting from scratch, especially don't quit your job. It took me two or three months to find my current job, and I was on a short leash for a while. I have been working in this front-end job for less than a month, so I am still a novice in the front-end, but I promised to share some web front-end things with the manager, so I will briefly talk about the content related to web front-end development so that electricians can also understand the front-end. There are many experts in the forum, please don't laugh at me. If there are any mistakes, please forgive me and correct me. The front-end of the web has only emerged in recent years. The reason for this rise is probably the widespread use of AJAX and the improvement of browser performance. Many tasks that are more suitable for front-end processing have been transferred from the back-end. The emergence of node.js has also given JavaScript a place on the server side, and front-end technology is still expanding into desktop applications and mobile applications with the help of some frameworks, so the front-end has become popular. The basis of the front-end of the web is nothing more than three major components: HTML, CSS, and JavaScript (JS for short). HTML is the content, CSS controls the presentation of the content, and JavaScript is the most powerful and can control everything. HTML is the cornerstone. A page can be without CSS and JS, but it is impossible to be without HTML. CSS and JS are both introduced through HTML. The content of HTML is also relatively simple, just some basic elements, such as

Among these, some essential ones are html, head, and body. If these elements are not present in the HTML file, the browser will automatically add them. The first line of the HTML file should declare the content of the document, usually to declare that it is an HTML5 file. After the browser knows the document type, it can parse the document according to the corresponding rules. The next heavyweight element is the head . It is necessary to inform the browser of the text encoding type of this document as early as possible so that the browser can parse the document faster, so this element should be placed in the first position of the head. HTML5 introduces more semantic tags, as well as some special tags, such as

I know why there are so many advertisements on the forum. The '&' character in the post content is not escaped, and the entity characters I wrote are eaten up and displayed.

Since few people read it, I won't change it.

The captain is awesome, I just passed by

I read this article carefully. The frameworks mentioned by Yagami are good. I think I will take a look at these frameworks after I am familiar with the basics. Is JS not complicated? I can download special effects from the Internet, modify them myself, and use them, right? Has anyone written those complicated special effects?

Congratulations to the captain for his successful transformation. Look up to the top management.

Just treat it as an extension. After one year, the front end is not as good as the embedded system. It is neither high nor low. It still has to go up or down. Although it is very hot and popular, ST is also popular, but popularity cannot prove that they are not garbage. Although the above is not pleasant to hear, it is the fact. I just want the captain to have a smooth career. The only purpose is to wait for the captain to sell the board for 5 yuan.

Writing code is completely different from the previous paragraph. Writing code is too broad, and the previous paragraph is very narrow. It is precisely because of the narrowness that I have extra time and energy to read so many books in other languages and other fields. Captain, just be happy, and go ahead.
