Type checking embedded expressions in tsx

[ceymard]

It would seem that typescript treats anything between curly braces in tsx expressions as any.

There is no option on the JSX namespace that I know of that allows restricting the result of expressions to certain types.

TypeScript Version: 2.2.1

Code

var div = <div>
  {new Date()}
</div>

This always compiles. How do I prevent certain types from being validated there ? Should there be a modification of the JSX namespace ?
