>Okay so it's coupled to Microsoft's take on Javascript. What about Flow or any of the other compiles-to-Javascript languages? What's wrong with using Babel with sourcemaps? This is kind of like saying "Oh it supports Javascript? So now I'm tied to Netscape's take on browser scripting?" at this point. Typescript has won the JS compiler wars and become the defacto standard for the community.

Which slightly incompatible version of TypeScript though? edit to add: I'm serious. JavaScript tries very hard to not have backward breaking changes. TypeScript does have breaking changes at about ever minor release. The TypeScript team manages the project as a versioned tool, not as a distributed environment like the web. afaik, Deno hasn't really solved this problem, so there's a chance your code breaks when Deno upgrades its TypeScript version.

  That's always a concern, though. Node has breaking changes, too.

  It's a somewhat relevant concern, but also less so because breaking changes in TypeScript are usually semantic (type-checking) ones and most of the times make it error on bugs (i.e. code that hopefully isn't in your codebase already, and if it is, you'll want to take it out). Deno doesn't do type checking, it just strips TypeScript's type annotations, which they're far more careful about breaking. Even so, they could limit such breakage to major Deno versions with other breaking changes, if necessary. Not sure if they do.
