Why does the return statement call the variable name not the function name?

For example why can't I write: function sayHi () { var helloDay = alert("Hello"); return sayHi; }

We always want to return a result of some sort. Saying return variableName; means we want to return the value of variableName. In JavaScript, using the function name would return the "value" of the function, which would be the whole function itself.
