inside {}, we can write anything without making Variable?

const name=prompt("what's your name?") const message=hello, ${name}, It's ${2*4}. console.log(message); like this, can I use ${} anytime without assigning Var as long as string is inside tick marks??

when you make a template literal like that, the ${} acts as a placeholder.

anything in between the curlies will be parsed as javascript, so yes, you can do something like:

console.log(`The sum of 8 and 4 is ${8+4}`);

or 

const a = 8;
const b = 4;
console.log(`${a} + ${b} = ${a+b}`);

or even

const a = 8;
const b = 4;
const sum = (a, b) => a+b;
console.log(`${a} + ${b} = ${sum(a,b)}`);
