Is there a way to change a ” string in a “ string?

Take this object as exemple

item = {'field': 2};

I have a '${item['field']}' string. This, in JS, is just a string the way it reads, but I actually want the content of the field, so is there a way to make this change?

'${item['field']}' ->  `${item['field']}` 

So that it prints 2 instead of ${item['field']}
