> But I will not recommend any other people (non-JS) to use TS at all JavaScript, and increasingly in the Typescript flavor, is the language of the web. What real alternatives are there presently, that additionally gives a developer decent career opportunities? TS vastly improves on JS in most aspects, while keeping a 100% compatibility with pure JS, i.e. you can just change the extension of a working .js file to .ts and instantly get access to the TS goodies. You seem to complain about this compatibility, but a serious TS developer will not maintain such compatibility for long (will typically start restricting 'any' type, etc). This compatibility is the effect of the TS onboarding strategy, a crucial one at that. The typeguards problem you mention is just one of the problems a JS/TS developer deals with as a matter of course, and will usually have solved by creating/using a utility library, something which JS notoriously requires, and something TS doesn't aspire to help you with, for the same above mentioned compatibility reasons.

> JavaScript, and increasingly in the Typescript flavor, is the language of the web. What real alternatives are there presently, that additionally gives a developer decent career opportunities? As a Scala developer who realised the writing was on the wall for server-side rendering, I spent a good few months trying to use Typescript. It's decent, but the type system was still a huge step down from what I was used to. A month or so ago I got around to trying Scala.js, and it was... nice, and oh so easy. Facades available for all the big-name javascript libraries. Write ordinary Scala code with the advanced type system and full IDE support that I was used to, and get the same ability to rule out huge classes of errors that I have on the server side. So, Scala? It's controversial for many but it supports a lot of development styles, uses a runtime that already has a lot of enterprise backing (and will be able to interoperate with your existing libraries if you're a Java shop), and is also used for various bits of exciting newish technology (Kafka, Spark and the like). So it definitely has decent career opportunities.
