Once type annotations land natively in JavaScript, TypeScript will go the way of CoffeeScript. Unless TypeScript can almost double overall adoption in the next 2-3 years, this is a confident NO.

@nettika It'll get type annotations, sure, but all that means is that you won't have to strip the types from your code anymore. You'll still need to pick a type checker, and I'd be very surprised if an alternative overtook Typescript in that role anytime soon.

@Solecontro what if some other language is number 1, but typescript beats JavaScript?

@BoltonBailey I wrote in the description that for this market to be resolved as YES it must be #1

Will count as a YES if Typescript is in #1 position in the end of year Octoverse report

@Solecontro Thanks. Just wanted to clarify that the market is not only about overtaking JavaScript. Another question: is this any year before 2030, or just the 2030 report? If typescript were to be number 1 next year, I would probably say it had become most popular “by 2030”.

@BoltonBailey That's a good point - yes, if it happens at any point before 2030 this will resolve as a YES
