function declarations aren't the only thing that is hoisted, variable declarations with var are also hoisted.

e.g. the following does not work:

console.log('hello', future());
const future = function() { 
   return ' world'; 
}

This gives you more freedom on how you structure your files. You're not forced to declare functions on the top, and instead can have the most relevant code on the top which can make the code easier to read.
