Honestly, it makes a ton of sense for Microsoft to buy GitHub. After this acquisition, they will control:. - VS Code.- TypeScript.- Electron.- GitHub. This puts them pretty much front and center of the modern development stack for a lot of people.

If coding doesn't feel like being totally lost and having no clue what you're doing, followed by hours of trying different things and short bursts of stuff kinda working, you have at least another level to master before calling yourself a programmer.

The word is "compile", not "transpile". They mean the same thing. JS developers invented a new word because they weren't used to working with compilers before Babel came out. But "Babel is a JavaScript compiler". So is tsc. That's what the "c" stands for; compiler. Ofc, it

Who’s going to tell him about Cloudflare?.
@levelsio All the people getting bigger bills are GENERATING AND CACHING TENS OF THOUSANDS OF HTML PAGES ON A CDN. Literally none of that is possible on a VPS without also spending lots of money and time on a CDN. If your web service can comfortably run on a $5 VPS, it will almost.

No matter how many times I setup all the configuration in a new JavaScript repo, each time feels like the first. Lots of Googling and re-learning stuff I used to know. Babel, Rollup, ESLint, Jest, etc. This stuff just doesn't stick in my brain for some reason.

No joke, about 95% of the work in open source is around education. Docs, issues, pull request reviews, web sites, blog posts, talks, tweets, examples, etc. Writing the code is the *easy* part. Helping people use it is the vast majority of your responsibility as an OSS dev.

Most common mistake software developers make: putting stuff in the wrong place. Coupling responsibilities and concepts that should be kept separate. For me, this is 95% of software development. Just figuring out *where* things belong.

So, React recommends:. - you should use a framework with React.- frameworks should pin to a canary version of React in order to take advantage of the latest “stable” features that do not yet appear in a stable release. I have no idea how this is going to play out in the Remix.

I’ve been seeing more and more people bemoaning the widespread use of React lately. Wishing for something else to come along. Don’t forget: the underlying tech is HTML!. Treat React as just a tool for generating and manipulating HTML and you will have a much better time with it.

If you're building JavaScript tooling (I'm looking at you @bunjavascript and @CloudflareDev, maybe others 😇) please, please default to .json config files, not .toml. JSON is *infinitely* more readable than TOML for JavaScript developers. It's our native tongue.

Unpopular opinion: All that junk you're putting in React context should just be props. Legit uses for context are rare, and mostly for library code, not your app.

Everyone quoting this and talking about how their Node.js/PHP/etc app can outdo this perf-wise is just showing their inexperience. Serving an app the size of basecamp with a mean response time of 90ms is no small feat 😅.
Basecamp did 5,250 req/sec at peak yesterday. Mean response time was 90ms. So call that needing 500 cores at max load. If you skipped redundancy, you could probably do that with 3 boxes each running a Z5 192-core AMD chip with room to spare. Servers have gotten crazy fast!.

The refusal to acknowledge HTML and CSS as "real" programming languages has done more harm to the web than probably any other gatekeeping tactic. Both are incredibly capable and very *real* languages! Both require years to truly master.

Microservices are an indication of organizational issues. They are an escape hatch for engineers who don't have the power they need to do their job correctly, so they try to break off a tiny silo. Over time, you incur tremendous overhead from all the fragmentation.
@EricFrohnhoefer @MEAInd True, the food is great. The fact that you don’t realize that there are up to 1200 “microservices” being called when someone uses the Twitter app is not great.

I used to look at weird engineering solutions and think “huh that’s weird why didn’t they just do <something else>”. Now I think “I wonder what constraints they had that I don’t know about”. Instead of assuming other people are incapable, assume they are operating w/ constraints.

Counterpoint: Java (Scala) microservices we’re an absolute nightmare for us at Twitter as we migrated off Ruby on Rails. Much of the complexity that Elon mentioned after he bought the company was from this architecture.
At @Airbnb, while we appreciated the flexibility of Ruby on Rails earlier on, it absolutely became unsuitable at scale (both traffic and organizationally) and we had to work miracles while replacing much of it with java microservices.

It’s totally fine to disagree. But you don’t have to be mean about it. Kindness is important. It’s not just a nice-to-have. It makes a tangible difference in discourse. Kindness is what most people are missing when they lament the state of social media. KINDNESS MATTERS.

The difference between `null` and `undefined` in JavaScript:. `null` is actually a JavaScript value (object), whereas `undefined` indicates the absence of a value. You can see this if you try to JSON.parse them:. JSON.parse('null') // null.JSON.parse('undefined') // SyntaxError.
