Nested string interpolation is broken in TypeScript

[pkaminski]

When trying to nest interpolated strings in TypeScript the string never gets "closed" and the rest of the code doesn't get properly formatted. Here's a repro using highlight.js 9.12.0: https://jsfiddle.net/91twpfa2/3/ Note that this works correctly with the language set to JavaScript so hopefully just needs the relevant fix applied to the TypeScript language definition.

I took a peek at this the other day. The typescript definition is missing the concept of substring nesting that exists in the Javascript language file.

Relevant lines in languages/javascript.js and languages/typescript.js

It'd be easier to see the difference if the typescript language file were refactored a little to match the JS file.

I forgot to mention it on the PR, but this should be fixed by #2105
