There's no such functionality indeed but you might want to have a look at
this gist: https://gist.github.com/WebReflection/8f227532143e63649804
It gives you the ability to write `'test1 ${1 + 2} test2 ${3 + 4}'
.template();` and read `test1 3 test2 7` or to pass an object similar to
.Net String.format so that your Stack overflow code would be like the
following:
```js
let a = "b:${b}";
let b = 10;
console.log(a.template({b:b}));
// or
console.log(a.template({b:27}));
```
You pass named properties and it works with nested properties too (i.e.
${down.the.road})
It does use Function which is safe, compared to eval, and needed to
eventually de-opt from 'use strict' but of course you could write your own
parser avoiding Function completely.
Finally, I agree it would be nice to be able to have a standard way to
template strings in JS, the templating as it is plays very poorly with
runtime generated strings, using eval for that looks the dirtiest thing on
earth.
