Mixed compilation of typescript

Question

I want to compile typescript code to any target (ES5, ES6 or newer), but with this mixed target features applied simultaneously:

• Template strings should be kept as is.
• Arrow functions should be kept as is.
• const and let keywords should be compiled into ES5 (var and clousure function).

Is it possible and how I should update my tsconfig?

Answer 1

Is it possible and how I should update my tsconfig?

This is not possible via configuration. With a specific target es6 you get all these features as is, and with target es5 they all get transpiled into something ES5 can run.

I cannot think of any JS runtime that would support template strings as is but not support const and let.
