Wow, 39.9% of respondents mark themselves as "Expert" at CSS. I've been doing front-end in various guises for 12 years and I would only rank myself maybe 5 or 6 out of 10. As I've gotten more experienced in my career I've become more aware of what I don't know as opposed to what I do know. It's funny that "Advanced" is mastering animations and transitions whereas "Expert" is being able to develop a full-front end con…

The description of "Expert" in the survey probably caused this. "Expert: Being able to style an entire front-end from scratch following a consistent methodology" Meanwhile, "Advanced: Mastering animations, interactions, transitions, etc." I can certainly "style an entire front-end from scratch" without "mastering animations".

Exactly my reaction. I do think that you can create stunning animations and for that you need some expertise but animations are the "the basis" for a complete and successful front-end.

I've been taking job applications from other frontend developers in the Silicon Valley fortune 500 area of work. Most resumes that get past the initial recruiter interview and make it to a tech review and claim expert knowledge of CSS... They don't. They don't know shit. They can often not answer basic flexbox questions. Not to mention CSS grid questions. And if you start questioning them about CSS animation performa…

> I could go on and on about the horror that is typescript

In his talk Predicting the future of the web at the last ReactiveConf, Richard Feldman (not himself a typescript guy, but an Elm user) quoted an interesting statistic that most of developers who try typescript never go back to writing plain javascript. I do not remember where that statistic was from, but can attest that with me it is the case. So much for the horror that is typescript.

> I could go on and on about the horror that is typescript As someone who has seen great improvements in delivered productivity and quality across an entire organization, more or less due to Typescript alone, I would be eager to hear what your complaints are.

The saving grace of Typescript is that types are optional. If types were mandatory for everything, it would be very hard for me to get a buy-in.

I got a resume a while ago where the applicant rated their skills 1-5 stars. They has rated themselves either 3 or 4 out of 5 in Node.js. When asking what they actually did with node, they explained they built some proof of concept once. I got to see the code and it was maybe 4 weeks of work for a beginner... At that time I was leading a small Node.js dev team and I would maybe rate myself 3/5 in Node. We didn't end…

To be honest the problem here is the question not the answer. It’s a bad question and shouldn’t be asked.

Why is it bad to ask about the actual experience someone had with something that I will be hiring them for? That makes no sense to me.

Typescript doesn't make things easier, and react is intuitive? You know April fool's is still a few months away right?

TypeScript slows down a project. Nobody seems to ever point out what benefits it supposedly offers. My claim: TypeScript offers no benefit. Ever. That's 2 years of fulltime TS experience talking and 18 years of fulltime JavaScript experience, on top of a whole bunch of full stack (Java and .Net with C#) experience. I think the popularity of TS is going to decline. And I think it's only popular because of the influx o…

Types slow you down a bit at the start, but speed you up forever after that. Untyped projects are fast to whip out, but slow piles of undefined behavior forever on. Oh and add unit tests, without types, and all you have is a checksum.

> And I think it's only popular because of the influx of backend developers coming into the frontend.

That's not the only reason why it's popular.

Aren't you describing exactly the problems types help with? Must be a reason why typed backend developers allegedly don't pay so much mind to: - "proper" naming conventions - JSDOC comments - unit tests - peer review

So, I've worked with JavaScript since 2001. Up until two years ago I never used a strong typed flavour on top of JS. And I have never needed it. Not in big teams and not in small teams. At work we recently did a timed programming problem solving competition. 20 Teams got 1 hour each to solve multiple levels of the same problems. Some teams used TypeScript. None of the TypeScript teams got past level 5. All of the res…

Yeah, Typescript does slow a project down.

It's not even about using types. Sometimes you get stuck trying to resolve Typescript issues that are not part of your core problem.

Redux has the largest shift towards "negative opinion" out of all technologies. Did people just get fed up with the boilerplate or is there something else going on?

Redux is a bit like Java: it's possible to write well-designed software with it, but it's also gotten a reputation for being used by the sort of programmers who blindly apply "best practices" and create nine layers of AbstractFactoryGeneratorBeans for everything.

I suspect one factor in this is that if you know enough to apply Redux's patterns well, you probably also know enough to implement them yourself without bringing in a third-party NPM package. (Of course, not everyone will choose to do this --- maybe you like the Redux debugger UI or something --- but I think enough people do that it lowers the perceived average quality of codebases that do use Redux.) The library just doesn't do anything difficult in the way that, say, React's virtual-DOM diffing and reconciliation algorithms are difficult.

Half of my income is from training people in JS and Python. I have 50% of those missions that are requested to be "advanced" courses. The vast majority of the participants are not up to the task. They are paid professionnals, but they consistently overestimate they level, skills and needs. They often are not very good, and of course, they don't know what they don't know. So I always check for that first, and rewrite…

One thing I miss about university is exams.

I miss being able to focus for just 2 hours on a task that would then give me a clear view on how well I knew the important mental models of a topic.
