Technical trendsetter

Nowadays, technology is updating rapidly , All kinds of frames 、 Tools 、 Languages are emerging one after another . Especially front end technology , In three to five years, it will be basically renewed . We often hear the development partners sigh 「 I can't learn. 」, At the same time, they are constantly chasing these new technologies . After all , If you don't want to be eliminated by this era , You have to constantly update your knowledge system , Without stop 「 Roll up 」. But one's energy is limited , It's hard to learn all the new technologies . therefore , Some people start to worry ......

Follow the fashion

A new technology is on fire , Do I want to study ？ I have often asked myself this question . Of course , Pursuing new technology is definitely a good thing , But fire learns what it is , The final result is not necessarily better than standing still .

Because it may cause waste , Put your energy into technologies that you can't use . Just like the pursuit of new mobile phones , Replace the old one as soon as the new one comes out , If you do have money and willfulness , It doesn't matter. Just change it , If we don't have much money, we still have to save some money . The same is true of learning new technologies , If your energy is limited , Then meet the demand .

“

Whether a technology is hot or not should not be the reason for us to learn it , At best, it adds an option to our list of choices , When we have a need , It's not too late to learn .

Out of date

Some technologies , It's out of date when you use it . Only a short while ago ,Redux When he was born, he had boundless scenery , Once upon a time React Standard configuration of the project . however , Now in the project Redux May be scolded 「 Spicy chicken 」. I remember once we JS The crowd blew up , Everyone is roast inside Redux Long time .

you 're right ,Redux There are a lot of problems in using it , A lot of template code 、 It's tedious to write 、 Easily confuse state and view relationships 、 Make components difficult to reuse 、 It's easy to write bad code and so on . however ,Redux After being out of date , Is it really useless ？ I don't think so . Even if Redux Outdated , It brings ideas and solutions , We can still learn from . such as Redux It's solved React The difficult problem of sharing state across components , Users can subscribe to Store To update UI, It was the first time to introduce middleware Mechanism and so on .

With these foundations , We can pass quickly React Context API and RxJS Create a better global state management tool . however , If you can only use a few Redux Of API, Did not understand Redux And the problems it solves , So when the tide recedes , You may have nothing left .

“

Tools are temporary , The idea is long-term .

New use of old medicine

Some technologies are out of date , Some technologies are 「 A stirring among the dry bones 」 了 . Earliest JSP Time , We use the server to render , Because of AJAX Appearance , Make the front and rear ends separate ,SPA It began to prevail . however , As for SEO And the first screen loading performance , We started to turn to server-side rendering again .SSR suddenly , It has become what we call 「 new 」 technology , It's just that the implementation has changed .

similarly , also CSS In JS, At the earliest we will CSS and JS Wrote together , Later, he advocated the separation of style and performance , Because at that time, we expected that when we changed the style, we would not change the logic . however , With the increasing complexity of front-end interaction , We need to organize the code in a componentized way , Reuse styles by reusing components , So it will CSS and JS Together, it has become a new trend .

“

Times are changing , The old and the new are changing .

Orient

While pursuing new technologies , It is also important to learn the underlying technology . We all know 「 It is easy for the bottom technology to learn and understand the top technology 」. That's right , But there are many underlying technologies , What is the most appropriate thing to learn ？ We need to determine our own direction first . If your goal is to learn React, So computer network 、 Underlying technologies like operating systems may not help you much , but DOM And browser rendering principles may give you a deeper understanding React The design and principle of .

“

Although the underlying technology is important , But since you can't eat at one go, you can't be a fat man , We need to prioritize according to our direction , Gradually accumulate and precipitate .

Grasp a typical example and you will grasp the whole category

When you master a skill , This technology can help you quickly migrate to other technologies . such as , As React developer , Suddenly want to learn Flutter, You will be in Flutter See in React Common things in , Life cycle , Global state management ,Context, And even Hook Widget.

At the end

New technology still needs to be learned , But we need to find our own direction first , Then focus on your own direction , Continue to precipitate yourself by extending relevant underlying technologies , On this basis, learn some new technologies , It may make you more comfortable . Last , Instead of following the trend , It's better to create the trend by yourself . If given the chance , You can create or participate in some open source projects , Maybe one day it will lead the trend .
