Answer 1

/*
The reason is that 'height' is a function, so assigning it as is to a variable will store the reference of the function itself... to call a function, you need to append a parenthesis pair after its name, so the function is executed, and the returned value is stored in the variable ^^
*/

function myfunction() {
return 42;
}

var a = myfunction;
alert(a); // show the function source code, because a hold the function itself, and default cast to string will show its code

var b = myfunction();
alert(b); // output 42

// but with 'a', since you've assigned to it a function reference, you can now do:

var c = a();
alert(c); // output 42

// or shorter:

alert(a()); // output 42
