5 years ago, Mattias Petter Johansson – better known as MPJ – was already a well-known developer.

5年前，Mattias Petter Johansson(众所周知的MPJ)已经是著名的开发人员。

He had made a name for himself by answering hundreds of coding questions on Quora. And he had gone from theater student to prolific developer, having built a product that was acquired by Blackberry.

他通过回答有关Quora的数百个编码问题而为自己取名。 并且他从戏剧学生变成了多产的开发人员，并开发了被黑莓(Blackberry)收购的产品。

So in the summer of 2015, MPJ was working at the height of his field as a front-end developer at Spotify in his native Sweden.

因此，在2015年夏天，MPJ在他的家乡瑞典的Spotify担任前端开发人员的鼎力工作。

And that's when he decided – seemingly out of nowhere – to launch a programming YouTube channel.

从那时起，他决定(似乎一无所获)决定启动一个YouTube编程频道。

I distinctly remember sitting in my parent's living room with some hot tea when his first video went live. And of course I clicked on it. Because how can you not click on a video called Fun Fun Function?

我清楚地记得当他的第一个视频上线时，坐在父母的客厅里喝些热茶。 当然，我单击了它。 因为您如何不能单击名为Fun Fun Function的视频？

"Hello!" MPJ shouted exuberantly in his first video. "In this video series, I will teach you how to do functional programming in JavaScript."

“你好！” MPJ 在他的第一个视频中大喊大叫。 “在这个视频系列中，我将教你如何用JavaScript进行函数式编程。”

Little did any of us know at the time that this "video series" would stretch on for 5 years, span more than 200 episodes, and ultimately become MPJ's full-time focus.

当时我们几乎没人知道这个“视频系列”将持续5年，跨越200集中，最终成为MPJ的全职焦点。

为开发人员社区提供大量的编码乐趣 (Gifting The Developer Community a Trove of Coding Fun)

In addition to functional programming, MPJ covered lots of other programming topics.

除功能编程外，MPJ还涵盖了许多其他编程主题。

Throughout the show, there were two reliable fixtures: MPJ's high energy, and his ever-changing hair color.

在整个演出中，有两个可靠的装置：MPJ的高能量和不断变化的发色。

Over the years, MPJ did cross-overs with some of the most exciting teachers in tech.

多年来，MPJ与一些最令人兴奋的技术老师进行了交流。

He also shared lots of insights around how to break into the field of software development, and how to continue to progress with your career.

他还就如何进入软件开发领域以及如何继续发展事业分享了许多见解。

所有美好的事物都必须结束 (All Good Things Must Come to an End)

So today, it was with mixed emotions that I watched his final video.

所以今天，我看了他最后的录像时充满了喜怒无常。

If you have 15 minutes, I encourage you to watch the video – even if you've never watched his channel before. Because this is a master class in how you responsibly and decisively bow out of a long-running project.

如果您有15分钟的时间，我鼓励您观看视频-即使您以前从未看过他的频道。 因为这是您如何负责任地，果断地退出长期运行的项目的大师班。

I probably learned more about MPJ and what kind of person he is from this video than I did from all his other zany, thoughtful videos combined.

我可能从这个视频中学到了更多关于MPJ的知识，以及他是什么样的人，而不是从他所有其他滑稽而周到的视频中获得的。

不管你有多好，你仍然可以变得更好 (No matter how good you are, you can still get better)

MPJ is a passionate developer who loves coding and loves teaching. All of this shines through in his videos. But he is also someone who sees his life's work as largely unfinished.

MPJ是一个热情的开发人员，喜欢编码并且喜欢教学。 所有这些都在他的视频中闪耀。 但是他也是一个人，他认为自己一生的工作还没有完成。

He has the humility to realize the limits of his own abilities, and to continue exploring and expanding past them.

他谦虚地意识到自己能力的极限，并继续探索和超越自己。

As he explains in his final video:

正如他在最后的视频中解释的那样：

"When I started Fun Fun Function I was still at Spotify, and it was a little bit of an outlet for me to talk about musings while I was at Spotify building.

“当我开始玩Fun Fun功能时，我还留在Spotify，当我在Spotify大楼里谈论沉思时，这有点麻烦。

更高的呼唤 (A Higher Calling)

Most importantly, MPJ wants to play a part in addressing an important challenge facing humanity – the challenge of mental health.

最重要的是，MPJ希望在应对人类面临的一项重要挑战–心理健康的挑战中发挥作用。

He explains:

他解释说：

"I want to go back to building products, putting things out into the world, and spend some time thinking about what it is that I care about. What is it that I should be creating?

“我想回到生产产品，将产品投放世界，花一些时间思考我关心的是什么。我应该创造什么？

I don't talk much about this on the channel, but when I was in my late teens, my mother committed suicide. It was after a very long battle with chronic depression and addiction to benzodiazepines.

我在频道上谈论的并不多，但是在我十几岁的时候，我的母亲自杀了。 这是在与慢性抑郁症和对苯二氮卓类成瘾的长期斗争之后。

During the last year or so I've been going to therapy myself, facing a lot of inner demons that have been there for many many years. And as I've done this I've realized what a big, interesting, important problem mental health is. I've grown the opinion that mental health is an area that way more people should be working on.

在过去的一年左右的时间里，我一直在自我治疗，面对许多已经存在多年的内心恶魔。 当我这样做时，我已经意识到心理健康是一个大的，有趣的，重要的问题。 我越来越认为心理健康是一个应该让更多人从事的领域。

We may not get any more Fun Fun Function videos, but it is heartening to know that people like MPJ are out there working hard on the big problems facing humanity.

我们可能再也没有获得Fun Fun Function视频了，但是令人振奋的是，知道像MPJ这样的人正在努力解决人类面临的重大问题。

And I will always be grateful for the many insights MPJ has left us with.

对于MPJ给我们留下的许多见解，我将始终感激不尽。
