推荐理由:页面写完了,该过一圈测试看看有没有漏洞了。这个项目允许你为自己的浏览器页面编写测试,并将测试过程信息等和页面一同显示以方便查看过程。对于原因诡异的预测外行为来说,回放之前进行的一系列操作自然就更容易找到产生错误的那条线,而从这里开始试着编写测试也是一种选择——毕竟在接触到复杂的页面时,编写测试是不可避免的。

Ignore the Hype When Learning to Code

Do yourself a favor, and stop being distracted by new frameworks and programming languages

The truth is, I’ve stopped learning a technology dead in my tracks just to jump onto the next latest and greatest thing. For example, I stopped learning Angular to learn React, and I stopped learning ASP.NET 5 to learn ASP.NET Core. I wish I’d have slowed down and learned a technology all the way through before moving on to something else.

The above are two examples of me ruining what I’ve learned in the past just to jump on the latest-and-greatest technology stack. I had no real reason to do this — I just did it because I had seen somewhere online that React was better than Angular.

I was chasing this unreality based on other people’s opinions that one framework or stack was better than another, that companies would use a certain stack over another, and that I wouldn’t be able to get a job if I didn’t keep up with hype train.

This is not true because very rarely will you find a framework or programming language that can’t do what the other can do.

Today, tools are evolving faster than they have ever before. There are new web frameworks, ORMs, programming languages, client-side frameworks, and many more.

As a beginner, you feel pressured to learn as much as you can as fast as you can. This is good — if you do it the right way.

Don’t get it twisted: When I say to learn as much as you can, it means to learn as much as you can about one technology. Don’t learn a little bit about Angular and then move to React. Learn all you can about Angular, then move to React when you feel that you have to.

When I say “learn as fast as you can,” that doesn’t mean learn five things at one time. It merely means to take your time and learn as fast as you can. For me, as fast as I can means a set schedule of learning something for two hours a day. Some people can go faster, but I find that number comfortable for me because I am not exhausting my brain or getting tired of the content.

Most comments you see online about a technology being better than another technology are usually spawned from people that don’t know what they’re talking about. But you do come across some individuals that have good points on why to use a certain technology over another.

These people have usually worked with multiple technologies and have taken the time to learn them each individually. Most of these people have already learned to code.

When you see people say they left Angular to go to React or they left F# to go to C#, it’s mostly because they had a very rare use case that needed to be solved that the other could not handle. Most of those use cases are deep and something that you’re not going to run into for a while.

Just Sit Down and Learn It

Find a technology you’d like to learn, and commit to it without jumping around. If you want to learn Angular, pick a version, set a start date on your calendar, and then commit a set amount of time every week to learn it until you’re close to mastering the technology.

While you’re learning the technology, you’re going to see posts online about React releasing a new version and how it’s better than Angular.

You’ll see the post about how Vue released a new version, and it’s better than React. The cycle goes on like an infinite loop (no pun intended).

Fight the urge to not jump on the hype train … stick with your calendar and the framework/technology that you committed to learning.

If you learn Angular for six months and then drop it and jump to another tech, then you’re losing the value in mastering Angular — and you’re dropping months of hard work and dedication.

When Can I Learn a New One?

You’ll know when it’s time to drop the current technology you’ve been learning to learn another one. There are two main reasons that’ll tell you it’s time to move on to learning a new technology
  1. Use case — You may have a use case that the particular technology doesn’t support.
  2. Curiosity — You may have an overwhelming curiosity to learn something new.
Before you let the curiosity get the best of you, make sure you understand the big picture. For example, understand code and how it works as well as object-oriented principles before moving on to something else out of curiosity.

You want to master your chosen tech before jumping on board to learn another because most of the tech work in the same way.

When you master Angular (or whichever you choose), then learning React, Vue, or other frameworks will be easier because the high-level concepts are similar.

Depending on what problem the technology is targeting to solve, they all solve that same problem — just in a different way.

The same can be said for programming languages. When you learn C#, then moving to Python will be a lot easier because the same core concepts still apply. You have inheritance, properties, parameters, etc.

Mastering one piece of technology is all about understanding the big picture.

It’s understanding the placement of a compiler, how the components are created, how does the parsers work, etc.

Knowing all of these things will help you become a better programmer with the stack you’ve chosen. When you understand how syntax is compiled and what the compiler is doing, then you’ll have complete control over the language and how to manipulate it to get the result you want.

When you learn how JavaScript frameworks are rendered and interact with the DOM, then you’ll carry that same concept with you throughout your coding journey.

But No One Will Hire Me If I’m Not Using the Latest and Greatest

People who are just learning to program have a huge misconception about what it is companies are looking for. This makes sense because you’re learning to program, you’re not trying to get a job at a Fortune 500 company as the lead software engineer just yet.

The misconception is within the technology stacks that companies use. Just because you see a Stack Overflow survey saying that Angular is the most popular programming language at the moment doesn’t mean that all the successful companies are using it.

To be fair, a lot of companies don’t keep up with the latest and greatest because it’s so expensive to go back and change things. You’re not going to rewrite an entire code base just because of a new release that has a few changes and potentially many bugs.

When you have money on the line — not to mention customers, investors, etc. — you cant rewrite your entire application just to stay up to date with the latest hype. It can cause obvious issues and potential risk to the organization.

What Should I Learn?

Like I said in the beginning, pick a technology, and try to master it. It can be any technology — it doesn’t matter. There will be a place for you in the exciting industry of computer science.

I see job openings all the time that are paying high salaries for Ruby programmers, C++, and even COBOL; those technologies are many years old but are still in demand.

I promise all those technology stacks and frameworks you want to learn will be there after you master what you’d like to master. Just calm down, ignore the hype, and learn something to the fullest extent. So go, pick a technology to learn, and master.
