which and how javascript function will be called if we have 2 function declarations with the same name?

Question

Take a test:

Answer 1

(function () {

// even though not declared yet, every 'inner' function will be hoisted,
// and be available to the entire function
sing();

// variables are dealt with after functions, so say will be a string
// the order of declaration suggests this to be the case, but that isn't what matters
function say () { }

var say = "say";

// variables are dealt with after functions, so shout will be a string
// even though the order suggests shout should be a function
var shout = "shout";

function shout() { }

// both are functions, the latter one 'wins'
function sing() { console.log("sing1"); }

function sing() { console.log("sing2"); }

console.log(typeof say, typeof shout);

sing();

}())

Output:

sing2
string string
sing2
