Hi Luckius,

In your example, you are calling returnValue but not storing the result:

returnValue( " same value " );

To store the result, we need to use a variable. For example:

var echo = returnValue (" same value ");

Full code:

function returnValue( voice ) {
    var echo = voice
    return echo;
}

var echo = returnValue (" same value ");

We can refactor this code. There is no need to declare var echo inside the function, we can just return the parameter. For example:

function returnValue( voice ) {
    return voice;
}

var echo = returnValue(" same value ");

See JavaScript Scope

Hope this helps :)

thanks verry much,be blessed
