A few years ago I worked on a project that used Coffeescript; but because it had to be transpiled into JS the code I was debugging in the browser looked nothing like what I wrote, making it far more miserable to debug.
If/when not-JS can be natively debugged in all the major browsers (Chrome, Edge, Firefox, Safari) it might be time to consider an alternative; until then I'll stick with the devil I know. 
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

The question was 'Assuming you need to write JavaScript'
so I chose TypeScript because my understanding is that it has some form of type checking.

jQuery still offers some simple niceties that they have at best been jammed into javascript over the years.
$(".my-class").removeClass("jim");
let elms = document.querySelectorAll(".my-class");
elms.forEach(function(elm) { elm.classList.remove("jim"); });

… and would pass on any position that required it.
Weakly-typed languages are IMO too error-prone for production work, and any layer such as TypeScript is only putting lipstick on a pig.

Not only weakly typed, but interpreted as well. Both are evil. I detest both "qualities".
Tell me what I do wrong as I type, or at the latest when I run the compiler. Tell me for all my code, not just the code lines being executed at one specific run. Tell me where there might be problems - I'll flag it as OK if I know what I am doing.
The first C++ compiler I worked with compiled to K&R C (and the C++ compiler was written in K&R C). That way, Strostrup could in a single go offer C++ compilers for "any" machine regardless of instruction set or libraries. K&R C was treated like the instruction set of a virtual machine.
Maybe JS could be treated a similar way. Write your application in a typed, compiled language and have it compiled to the instruction set called JS, for execution on any virtural JS machine. That is the only decent way to make use of JS. You should be as much (or little) concerned about the JS instruction set as you are of the x64 instruction set.

I feel the same way about javascript that I feel about VB. Get a shovel, dig a deep hole, bury both of them, then bury the shovel!

Haters are going to hate.... 
All languages are just syntax. They are tools. Used properly, they work.
If you cut your toes off using the shovel, are you going to hate the shovel?
Or should you focus on your own lack of skill / inattentiveness while digging the hole?
Oh well....

When people write that about VB it just sounds like they're not very good at writing VB.

I was being facetious. I spent many years developing UI's with VB6. I figured with my wise ass comment I would make people's day and have some fun in the process.

Glad you're just joking, there are a lot of code snobs around who think VB/VBA are "toy" languages, just like whenever you post a question about MS Access the "geniuses" post comments like "Access is crap, use a real database like SQL Server or Oracle" etc.

I believe the main problem about this misconception is because you don't work with it. In fact if you take Stack Overflow's statistics JavaScript outweighs C# twofold and it's more used than any other language. I suppose if we extrapolate that fact we can assume there are more Javascript based production environments than anything else. It would be very dangerous to assume Javascript is not suited for production with the amount of work out there.
There are many ways to ensure good code quality on JavaScript with linters and automated CI tools that runs automated code analysis plus unit tests (if you don't do these, no matter the language you program in, you're in deeper trouble than the choice of language). If you have a good test coverage it almost completely mitigates the weakly typed disadvantages.

Not really. It's not a layer, in the end it's just a means for writing JavaScript in safer and more organized way. Which addresses some of the weaknesses of JavaScript. In the end TypeScript gets transpiled to JavaScript. So maybe, roughly 70% of programmers works with pigs

Given the quality of the code and especially designs I see daily I'd say that 90% of them should work with pigs - and stay the fark away from a computer.

Despite its many weaknesses, it also has many strengths. The trick to using Javascript well, it to know which is which. The best book I have read on Javascript (and in fact the only one I own personally) is "Javascript: The Good Parts" by Douglas Crockford. It's the only book you'll ever need.

No hooks in my code - works anywhere, everywhere.
The only frameworks I use (per the context of the question) are the ones I write myself.*

Web Development - C# in the Browser with Blazor[^] - being able to dump JS and run a "real language" with a good, solid framework behind it in the browser instead?
Gotta be worth it if it gets released properly.

That's why "if it gets released properly".

Somehow I suspect that a proper release will be the first of a million problems, especially those of an "Oops! It won't work with our browser (cos' we've made damn sure it won't)" variety.

I tried TypeScript, which I thought would solve all the problems I have with JavaScript, but it's really just JavaScript with more syntax.
Maybe it's something like Stockholm Syndrome, but I've come to appreciate the flexibility that JavaScript offers.
That said, I try to minimize it because it's still JavaScript

I tried TypeScript.. and just from the day 1 completely forgot about pure JavaScript
