>I think typescript is popular because it’s very java/c# like
I think at beginning it was mostly used by developers familiar with Microsoft stack (.NET world mostly). But TS was not designed for C# developers, it was designed for JS ones! And I'm super happy it's becoming more and more popular in more "mainstream" frontend community.
I'll just copy my old response to some very old thread that talk about why it not just "a language for C# developers":
"
Once sometimes asked me "Isn't Typescript a language for C# developers that don't know JavaScript" It's unfortunate that people think that TS is similar to C# just because it came from Microsoft. Flow language is like 80% similar to TS, but no one says it's similar to C#.
TS is just JS + new features from future JS specification + optional type system. And optional type system is fundamentally different than the one in C#, and it was designed to fit well with JS patterns and idioms (structural vs nominal type system)
If you look at TS code that looks like C#, it's because JS looks like that (classes syntax, classical inheritance, lambda syntax - it's all ES7 (or ES2016/ES2017, or whatever it's called now)
