I'm trying to re-use a template literal in javascript. 

This isn't working: 

```
let int;
let temp= `Number is: ${int}`;
console.log(temp)
// Number is: undefined
int = 1;
console.log(temp)
// Number is: undefined
int = 2;
console.log(temp)
// Number is: undefined

```

I thought that changing `int` variable will dynamicaly change in the template. but i learned otherwise :D

Is it even possible and if so what is the right way of doing it? 

Thanks.
