Replies to comments on my "LLMs are eroding my career" post
Are you sure about that? Most of the mid-2000's jQuery components bundled their HTML and CSS in bespoke template strings within JS. If you remember, jQuery had the `.css()` method accepted JSON to set CSS properties, and `.html()` accepted a string to set the inner-HTML.
And if you needed to manipulate strings to generate HTML, you'd be doing so with some kind of template mechanism, like string concatenation or substring substitutions. John Resig, author of jQuery, wrote Secrets of the JavaScript Ninja in 2008 [1], offering a small templating engine that does exactly that. The first commit in the Underscore library credits this book for their `template` method [2].
I think your chronology is skewed or confused. "SPAs" have been brewing in some form since the mid-2000's, when people stopped writing plain old HTML and CSS. Everything was jQuery UI widgets and AJAX, Prototype and Underscore templates. HTML died a very long time ago.

JavaScript evolution: From Lodash and Underscore to vanilla
If we compare the npm repositories for both packages, we can see that Lodash has a larger bundle size (1.41 MB) compared to Underscore (906kB). This means that when used in an npm project, Lodash would take an additional 500 kilobytes of network bandwidth while installing the node modules. But, with that additional size, we get some extra features. Let’s talk about them next.

KlongPy: High-Performance Array Programming in Python
There was a step-change improvement for me when I tried expressing some JS patterns via `underscore.js` instead of procedurally: eg: http://underscorejs.org/#each
Thinking of something as `each | map | filter | sum` is waaay less buggy than writing bespoke procedural code to do the same thing. No doubt there is a "cost" to it as well, but the _abstraction_ is valuable.
Now, if there were a "compiler" which could optimize that whole pipeline down and squeeze out the inefficiencies between steps because it could "see" the whole program at the same time. (oh, I don't know, something like `SELECT * FROM foo WHERE a > 100 AND b < 9000 LEFT JOIN bar ON ...etc...`)
...perhaps you could get both an expressivity gain (by using higher level concepts than "for" and "while"), a reduction in bugs (because you're not re-implementing basic work-a-day procedures), and an improvement in efficiency (because the "compiler" can let you express things "verbosely", while it sorts out the details of efficiency gains that would be tenuous to express and keep up to date by hand).

Not too far behind is Underscore.js, another utility library that's all about enhancing your JavaScript mojo. Whether you're dealing with arrays, objects, or strings, Underscore has got something for you. It's like Lodash's sibling, offering similar functionalities but with its own flair. The choice between them is like picking between chocolate and vanilla - it really comes down to personal taste.
