Javascript - named function declaration or assign to a variable?
in javascriptWhat's the difference between assigning an anonymous javascript function to a variable or just declaring a named function in the first place? Turns out "hoisting" of the function only works if you declare it as a named function in the first place. Assigning an anonymous function to a variable doesn't perform the hoist.

<script>
(function() {
console.log(f()); // 'hello'
function f(){
return 'hello';
};
})();
(function() {
console.log(f()); // undefined
var f = function() {
return 'hello';
};
})();
