What is the difference between the function declarations below?

var user = function () {
    //TODO: Some code
};

And

function country() {
    //TODO: Some code
};

Answers:-

The main difference is the function user is defined at run-time whereas function country is defined at parse time.

For example as,

<script type="text/javascript">
//WHEN WE CALLING USER FUNCTION HERE WILL THROW AN ERROR.
 user();

 var user = function(){
    alert("Hello, I am a user!");
 };
</script>

<script type="text/javascript">
//WHEN WE CALLING USER FUNCTION HERE WILL NOT THROW AN ERROR.
 country();

 function country(){

    alert("Hello, I am a country!");
 };
</script>
