Hey friend Mirali Mirzayev ,
First , you need to create a function that returns a value . Here is the code : 

function returnValue(name) {
  return name;
}

Now , you need to create a variable echo which stores the return value from the function . You can do this by calling the function with any argument , and then assigning the result to the variable echo like this:

const echo = returnValue("foo");

Here is the whole code: 

function returnValue(name) {
  return name;
}
const echo = returnValue("foo");

Hope it helped :)

Hello Sunny,

But why const, i actually tried it but instead of const i had VAR for variable. I am just little bit confused now.

Hey Mirali Mirzayev , both are right here.

const and let are introduced in ES6 , so it's just a newer syntax .
You will get introdced to them and lots of other changes too that made in ES6 , in upcoming courses , don't worry .
Till then you can use var .
And that doesn't matter here , what matters is you must store the returned value in the echo variable , which may be a var or const .
Hope it helped :)
