That first reply is so funny to me because it hits too close to home https://twitter.com/nice_byte/status/1466940940229046273 The more I do this, the more I gravitate towards the simple things.

New developers write simple but shortsighted code. It gets the job done, but it will be painful to work with in the future. Intermediate developers, bitten by their past mistakes, decide to future proof their work. But they don’t just look one or two steps ahead, rather they try to look five steps ahead and identity problems that do not and may never exist. Consequently, they over-engineer, over-abstract, and over-co…

I'm currently working with a team of Advanced developers for the first time in my career. Nobody is padding their CV with fancy shit. Everyone has gotten the "new shiny" out of their system.

Everything is as simple as it can be, no simpler and no more complex. Sometimes a bunch of flat JSON files in an S3 bucket is enough of a database, you don't need a 42 machine Aurora cluster.

All fancy "Machine learning" stuff really is just a bunch of ifs and for loops internally :D

That’s what disappoints me in modern Java. There is practically no ifs. It makes it inaccessible to beginners on the project, and the streams are about twice as slow… just because devs think they are more clever if they pile 7 “.map()” to transform a list. list.stream().filter(Objects::nonNull).map(User::getUsername).filter(Objects::nonNull).filter(name -> name.contains(searchString)).map(name -> “We have found your…

Modern Java looks horrible to be honest. I create abominations like this in JS pretty often, but it isn't good code. Best if wrapped in a huge try/catch where the error case juwt prints "didn't work for some reason...".

Hard disagree. For loops do not have guarantees about in-place mutation; that’s why they require a full read. Anything that starts with a map/filter is guaranteed to only apply to the thing that it is assigned to. That’s more than worth its weight in grey hairs. EDIT: “full read” includes “everywhere else this array is used, which can have far-reaching consequences if it was passed into the containing function by ref…

Most temporary variables are single assignment, and many newer procedural languages do have variable declaration syntax for single-assignment variables. Such as Javascript's `let`. Another wide-spread syntax feature is for-loops over collections like `for item in list`, again being extremely easy to read and not requiring any assignments. So, accidental in-place mutation is not an issue in practice. But, in-place mut…

JS "let" is not single-assignment; did you mean "const"?

Reminds me of biological metabolic systems. All loops and branches…

With a lot of fuzziness, some state and temporal stuff.

Yea, the fuzziness comes from protons shuttling about, tunneling around, electrons moving in cycles with phosphates. It's all just vibrating, bumping and bumbling about. I remember how blown my mind was when I first learned that all reactions catalyzed by enzymes would have happened anyway given enough time and the enzymes just tune the systems to work in concert in a time frame conducive to life.

Oops, guess you're right. I haven't written any Javascript in years.

And really, aren't loops just ifs and jumps under the hood? So coding is just ifs

Indeed. Jump on zero and integer manipulation are sufficient for turing-completeness. For example: https://en.wikipedia.org/wiki/Counter_machine

Can it compare two values and do one thing or another depending on that comparison? (IF)

Can it do something multiple times? (LOOP)

Can it change a piece of data?

Congrats, it's Turing complete.
