I think grandparent was referring to the fact that you can tell the compiler to ignore type errors if you so choose. The TypeScript compiler is perfectly happy to compile the code in your example, if you disable strict type checking and treat type errors as warnings. On top of that, there are simple annotations you can add that let you silence warnings as they come up, e.g. `const testVar: any = {}; testVar.asdf = "asdf";`. This is not too far off from a linter with comments to disable linting when you don't want it. So yes, technically, you can just run JavaScript through a TypeScript compiler.
