I received a question about this snippet of code:

function def(first="oldValue" , second=function(){
         return first;
}){
        var first="updatedValue";
        console.log('inside',first);
        console.log('function',second());
}

JavaScript function hoisting by example

Below are many examples of function hoisting behavior in JavaScript. Ones marked as works successfuly print 'hi!' without errors.

To play around with these examples (recommended) clone them with git and execute them with e.g. node a.js

Notes on hoisting
