Please stop. What a nonsense. JS is a dynamic language where everything is a Hashtable. It will never be really fast as your structs won’t be in single cacheline, you won’t be able to calculate field address during compile time by pointer offsets. There’s no simd, no multithreading, no real arrays.

JS is such a simple, dynamic language. It should just stay this way. Please stop bloating it with every feature that’s trendy this year. We already have classes that we didn’t need. We don’t need structs for sure.

I am not sure how to really refine this thought I have had, but I have this fear that every language eventually gets so bloated and complicated that it has a huge barrier to entry. The ones that stand out the most to me are C# and Typescript. Microsoft has a large team dedicated towards improving these languages constantly and instead of exclusively focusing on making them easier to use or more performant, they are c…

This is why always say the true beginner programming language is C.

Stupid easy to learn, have some loops, have some conditions, make some memory allocations. You will learn about the fundamentals of computing as well, which you might as well ignore (unknowingly) if you start with something like JavaScript (where is this data living in my computer?).

High performance applications are already being written that depend on features like shared memory, but because the language has poor support for them then developers have to use ugly workarounds. This proposal solves that with built-in support.

>It should just stay this way

Counterpoint: JS has been evolving significantly, look at ES6 and ES8 in particular if you need help finding examples.
