Why aren't template literals green in the code playground in JavaScript?

Question

//Try this code.
var tl = `4+5=${4+5}`; //This is a template literal.It is a type of string so shouldn't it be green in the code playground
document.write(tl);

Answer 1

that's actually a nice suggestion

try submitting it to SL ^_^

Answer 2

Just request it; I found a bug in their editor keyword suggestions a while back and they had it fixed by the next update -- but this would have affected a lot of people.

If it doesn't get changed...just note: I think template literals don't work on older javascript engines (making it a syntax / unexpected symbol error), so it may mean not enough mobiles support it.
