Over 10 years ago, I had this sort of a prediction that, with the massive adoption of a dynamic language like javascript on both client/server sides and test-driven development gaining a lot of ground, the future of programming would be dynamic and "feedback-driven". As in, you would immediately see the results of your code as you type, based on the tests you created. To naively simplify, imagine a split screen of your code editor and a console view showing relevant watch expressions from the code you're typing.
Instead what happened was the industry's focus shifted to type safety and smart compilers, and I followed along. I'm just not smart enough to question where the whole industry was heading. And my speck of imagination on how coding would have looked like in the future wasn't completely thought out. It was just that, a speck of imagination that occurred to me as I was debugging something tedious.
Now, most of the programming language world, seem to be focusing on smarter compilers. But is there some language or platform, that focus instead on a different kind of programming paradigm (not sort of OOP, FP paradigm, may be call it the programming workflow paradigm?). May be it comes with a really strong debugger tooling that's constantly giving you feedback on what your code is actually doing. Think REPL on steroids. I can imagine there would be challenges with parsing/evaluating incomplete code syntax and functions. So I guess, the whole compiler/translator side has to be thought out from the ground up as well.
Disclaimer: There's a good chance I simply don't know what I'm talking about because I'm no language designer or even close to understanding how programming languages and it's ecosystems are created. Just sharing some thoughts I had as a junior dev back in the day.
I've seen live updates for things like Go, NodeJS, Vue, Flutter, Angular, and you can recompile a Java class during debugging in Java (with limitations as certain things like static variables and methods need a full restart). More support and integration is certainly better but it doesn't feel like it's in a bad place to me.
I wouldn't say it's in a bad place either. Most enterprise grade technologies already have great debugging tools. Sure, those hot reloads, live updates are nice for UI development. But, I was thinking more of something built from the ground up to be, well, "feedback driven" in general. Most new stuffs that came out in the last decade touted their compiler as a killer feature first and rest of the tools are only developed as the ecosystem mature. May be that's just the best way to go about creating new successful language ecosystems, I don't know. Sorry if it feels like I'm being vague about the specifics. That's because I really only have vague ideas about whole the whole thing would work.
