Comment
Apologies if this is the wrong repository, I could not find one for the playground.
When setting the input language to "JavaScript", the playground does not show the transpiled code on the right. Instead, it shows the input code as-is.
You can test it by setting the target to ES2015 and writing 1 ** 2 in the input file: if the language is set to TypeScript you'll see Math.pow(1, 2) on the right (playground), while if the language is set to JavaScript you'll see 1 ** 2 (playground).
Is there a way to see the transpiled code?

Research direction
Start with the TypeScript playground's JavaScript input handling and compare it with the TypeScript path using the linked ES2015 examples. Done means entering 1 ** 2 with JavaScript selected shows the transpiled Math.pow(1, 2) output, matching the TypeScript case.
