On the subject of javascript template literals.

Do they really not support the equivalent to

    let template = 'hello ${name}';
    let n1 = template.format({ 'name':'joe' });
    let n2 = template.format({ 'name':'bob' });
    

I am not really a javascript programmer. but I was writing some and wanted to store a bunch of templates then fill them out dynamically and was unable to figure out how to do it with the native javascript template system. So I ended up having to write my own. As it appears to be a huge obvious hole in missing functionality, I have to ask. Am I holding it wrong?

While writing this up I was rereading the mdn page on template literals, perhaps tagged templates would do what I wanted, I don't remember why I did not use them(I think it is still not possible to store the template), but on first glance, yeah, lamentations about the unintuitive syntax and weird features.
