Technological learning

Prime not to heavy, day in the morning. When encouraged in time, time waits for no man. Time is always in our casual passage, 2021 is also quietly approaching the end, thanks to the nuggets remind, MY years trace has added a little.

  • JavaScript

It has been five years since I graduated in 2016, from ignorant at the beginning to ordinary now. I learned a variety of front-end frameworks and found that everything came from JS. The foundation is the most important. I also spent two or three months reviewing the js foundation and ES6. Briefly summarize the key points in JS, V8 engine working principle, scope chain, closure, prototype chain, this, browser, promise, async, await and so on. Even though we use these things every day, it’s rewarding to go back and relearn them. Fundamentals Fundamentals are really important.

  • vue

Vue3 has been out for a long time, and there is no systematic learning. Recently, I am not very busy with my work, but I have put vue3 system learning on the side. Composition API has become more and more like React, block Tree optimization has also improved a lot of performance, etc. Roughly studied the vUE source code, responsive, virtual DOM, diff algorithm, mount process, life cycle and so on. Simple implementation of their own mini-Vue, also can be considered to have a deep understanding of the framework.

  • react

The biggest gain of this year is learning React from 0 to 1. I used to use Angular all the time. This year, I learned React in my spare time and wrote a simple project. After learning React, I have to marvel at its flexibility, which perfectly reflects the ability of developers. React Hook is also very powerful without so many rules and regulations.

work

At the beginning of the year, I applied for a resignation and went out to see the opportunity, but I chose to stay for various reasons. Work flat light, but their own time a few more, more opportunities to learn. I always feel that my friends who are new to the industry will grow faster by doing more projects. If they sit for a long time, it will be better for them to use their free time to check their shortcomings. Keep it up.

life

2021 is a year full of surprises. The biggest trauma may be that I lost my girlfriend in this year and failed to introduce several people at home later. Maybe I am suitable for being single and not good at catering to others. The biggest change may be to exercise regularly, but I can’t go to the hospital. Money is not money here. I feel a little distressed, but more distressed for myself.

future

I hope that next year will be a good year for my work and my skills will be improved. I will update at least one article every month to share with you. As for girlfriend, let it be, maybe single is more suitable for me.
