Yes, ES6 brings the OOPiness
Just because you think that doesn’t mean it’s true. The sheer fact that TS has overtaken JS for the majority of web development says enough.
Has it? Or is that "just like your opinion, man"? Any citation? There's some sources that say it's more popular based on things like social mentions, etc, but that's a vanity metric. Perhaps the statement is true if you mean "web development" to be a very limited scope (like SPA using a build step), but I'm not even sure that's true then.
Obviously this doesn't apply to existing projects; you're grandfathered into the language barring a pretty big undertaking to move over, but if you go to any competent company doing modern web development on relatively new codebases, they will use TS over JS.
And if they don't, as an engineer, you should ask hard questions as to why not. Because if the answer is someone stuck in the early 2000s complaining about OO and strong typing not being needed, then that's completely missing what TS does (and especially what it did when it was released, which was pre-ES5) and how big of an impact it has to speeding up development.
