Can you add a variable to a string once the string has already been formed?

Is there a way to change the quotes of a string from double or single quotes to backticks in JavaScript after it has already been defined? I need to be able to add variables into the string.

I attempted using replace(), but it seems like the variable is not re-evaluated by JavaScript after the replace method is executed.

I am wondering if it is possible to achieve this dynamically, or if variables can only be manually added to a string in JavaScript?

Below is the code I have tried:

const variable = 9;

let strWithVar = "${variable}".replace(/"+/g, "`");

console.log(strWithVar);

The current output is:

${abc}

Perhaps consider the following:

let planet = "Earth";
let greeting = `Hello, ${planet}`;
console.log(greeting);
let person = "Alice";
let helloPerson = `${greeting}, ${person}`;
console.log(helloPerson);
