Template interpolation

I want to generate a TTS dynamically based on the input language

<script>
audio = document.getElementById("audio");
lang = "en_US";

audio.innerHTML = `{{ tts ${lang} word }}`;
</script>

the previous script generates a tts element, but couldn’t interpret the interpolated variable, i.e. didn’t replace ${lang} with its value.

there are some other issues here:
1- using let or var to define audio causes the script not to run at all

let audio = ....
var audio = ....
audio = ... // only this works

2- using double quotations also causes the script not working

audio.innerHTML = "{{tts word}}"; //not working
audio.innerHTML = `{{tts word}}` // working

Templates are rendered prior to being inserted on the page, so you can’t use JS to generate them.
