Jsliang 2020 Job Search Series

Hello, my name is Jsliang. I love to do things, learn and share with you. Jsliang’s self-introduction

Since 2018, Jsliang has had three front-end job hunting histories:

• 20020.09.01 Sorting out the third front-end job search (two-year student)
• 20119.02.01 Sorting out the second front-end job search (one-year student)
• 2018.04.01 Sorting out the first front-end job search in life (Fresh year)

During these three job searches, Jsliang experienced a variety of feelings: panic, confusion, anxiety, helplessness, relief and so on.

Like this one:

• Jsliang started his career in August 2020, where he set himself free and played around while writing a LeetBook.
• September began to enter review state, anxiety, irritability, how to review content so much?
• In the middle of September, naked face 3 small and medium-sized companies, was patter hit face, confused, helpless, my review progress how so slow, I am not suitable for the front end, I should not change.
• At the end of September, I had an interview with Shenzhen 360 Financial company. I was ashamed of myself. I answered the question, but I didn’t tell some knowledge points well.
• October National Day took a break to read two books: “Performance optimization” and “how the browser works”, admire, you are so nervous in the interview review, but also can calm down to look at these two e-books.
• In the middle of October to see the content of the preparation of almost, relieved, began to each content system over, supplement their omissions.
• At the end of October you will see the interview series finished, calm, calm, ask for a few more interview interview, let me try, I am not afraid to hit the face!

Yes, review 2 months, I still did not find a job, but my state of mind hasten stable gradually: what should review I reviewed, can enter factory son that see predestination!

On everyone’s journey, we can always meet nice friends and mentors. Here, I would like to give thanks to friends in the front-end industry:

• LinDaiDai_ Lin dull – boring review, thanks for your technical help and mood guidance
• Lien – Life may be slow, but the plan is always there
• Kacoo. – Try again. Almost done
• Lok lok – One year of experience is better than two years of working for nothing. It’s a pleasure to learn from you
• Qiao Qiao love learning – empty mentality, always succeed
• Tree jam. – Come on, help me push you in
• The rest of you. – Come on. Watch you

In this review journey, you are the mentor of your life!

Last year, before you, you have written some knowledge points that you are now vague, you need to humbly learn from the past.

Don’t understand ask, modesty makes people progress, why others a year ali P6, you two years or slag.

Even though you are so anxious that you are going bald, you have to believe that you can get through it.

How does the front end determine personal direction?

1. Analyze (current problems)
2. Build a library (build your own document library, store knowledge)
3. Calibration (determine your goals for the next 3-5 years)
4. To achieve (by making an effort to take the first step in time)

Again and again: Do not resign naked. Do not resign naked.

Do you want to go bald? Do you want to experience landslides and sinkholes? Let’s do the same as Jsliang.

About the way of review, here is to say that Jsliang is naked quit after all, may also consider more: just want to go to a better factory, and then toss about for 3/5 years, a better precipitation.

So jsliang is to review some knowledge points that will appear in the interview one by one.

If you want to review and organize, my personal recommendation is this:

• Step 1: Tidy up the JavaScript aspect

If your JavaScript foundation is not good, not familiar with closures, prototype chains and other content, or to Promise, Event Loop and handwritten source code control is not good, it is recommended to brush JavaScript points first.

Understanding the content is the first factor. If you don’t know what a deep copy is or what a shiver is, how can you write?

Also, don’t force yourself to memorize things by rote, like writing code by hand. You can type it out once, understand it, delete it, and type it out again.

So every time I review, I type the code more than twice.

Polling review method: 10.1 knock twice, 10.2 knock twice, 10.4 knock twice, 10.9 knock twice…… I think I’ll know how to write it.

Jsliang finds the Promise part difficult. The title and the handwritten Promise are based on the Promise A+ specification. The rest of the part is ok.

• Step two: Sort out the mainstream technologies you’re tracking

For example, the current company taps Vue or React, so follow up the content of that piece.

If you’re ambitious, you can do both (if you have enough energy).

Jsliang did not review Vue, but here are some points I can recommend you to read:

1. Vue Life cycle
2. Vue Diff
3. Vue bidirectional binding handwritten implementation
4. The difference between Vue and React
5. Vue vs. jQuery
6. The difficulties you encountered in the Vue project and your own highlights
7. …

As for React, you can just look at my arrangement on it.

• Step 3: Organize the browser and network aspects of your computer

With this in mind, Jsliang can actually be explained in tandem:

From the input URL to the rendering of the page, then introduce the browser’s local storage, browser caching, performance optimization, rearrangement and redraw, then introduce the computer network network security, DNS, HTTP, TCP, WebSocket, Speaking of WebSocket and network security then we can talk about cross-domain and garbage collection, garbage collection involves its collection mechanism LRU cache obsolescence strategy and so on.

So that covers my part of the story.

In addition, performance tuning can also involve Webpack, so let’s take the front-end engineering part of Step 4.

• Step four: front-end engineering content

In this section, it’s mainly Babel and Webpack, but as for the history of engineering Gulp and so on, I haven’t come across this kind of interview question.

Webpack knowledge is quite a lot. I think the important part is Webpack compilation principle, loader/ Plugin implementation and whether I have written it by myself. Then, hot update, Tree Shaking, Scope colliers and so on. Finally, the last is Webpack performance optimization, which I also have memory order:

1. WebpackItself.resolve.modules/extensions
2. Webpack 的 loader/pluginRelated: Caching, multi-process, multi-process compression, all kinds of content compression
3. WebpackOther related: lazy loading, hot updating,Tree Shaking,Scope Hoisting
4. WebpackOptimization help: Help visualize analysis of eachpluginSuch as

So these are the four parts.

• Step 5: CSS

Why specifically CSS and not HTML?

In fact, when jsliang was reviewing HTML, he noticed a new HTML5 tag and semantic content. He probably didn’t write much HTML and CSS, and he didn’t want the interviewer to ask.

So CSS part, often check some of the content will have vertical center layout, BFC and so on, here is not shiver, small friends can go to see.

• Step 6: Algorithm and data structure, design pattern

Some people might be confused by this, because you wouldn’t think about it at work, like Jsliang, a copy and paste engineer.

But jsliang is honored that he started his brush journey in May 2019 at the recommendation of his colleague Hao Brother, and became addicted to it. Now I have 470+ brushes.

But other friends also need not worry, in addition to the headline such as big factory, may ask you about sorting algorithms such as bubble, quick row, and what is red black tree, a simple review can look at these, of course, the above article I also wrote.

In addition, the design mode is also to sort out some knowledge points for partners, and then is to sort out the partners of Vue content, Proxy mode and publish and subscribe mode must see, Object. DefineProperty and Proxy to achieve two-way binding function, I don’t need to tell you too much

In this case, you should be reviewing all of this stuff. As for Node and TypeScript, it depends on the individual. After all, there are certain JD requirements that you must know.

Jsliang is only contact, do not show a fool, I wish the friends review like a duck to water, the interview is invincible ~
