/* Part I - Basic functions */

    // 1. Define a named function

    // 2. Define a function as a variable

    // 3. Define an anonymous function

    // 4. Define a fat-arrow function

/* Part II - Hoisting */

    // 1. Show how hoisting works within a function scope

/* Part III - Nested */

    // 1. Create a nested function which uses a parameter from the outer function in it's calculations

/* Part IV - Function invocation */

    // 1. Immediate invoke

    // 3. As method invoke

    // 4. As constructor invoke

    // 5. Indirect through apply() or call()

    // 5.1. Create a constructor function MobilePhone() which takes in manufacturer and size in GB

    // 5.1.1. Create a function called changeProps()

    // 5.2. Invoke changeProps() with apply()

    // 5.3. Invoke changeProps() with call()

    // 5.4. Assign changeProps() to a variable bound with bind() and call it

/* Part V - Parameters */

    // 1. Create the method sumAll() which takes in x many arguments and returns the sum (using arguments)

    // 2. Show how objects can be useful as parameters - e.g. given user print out namecard

    // 3. Assign a "static" variable to the function which can be used to get the next number

/* Part VI - Namespaces */

    // 1. Define a function as namespace and show how variables outside cannot be accessed

/* Part VII - Closures */

    // 1. Create a closure by providing a function which given a number adds it to the number in local scope
