for in loops over enumerable property names of an object. for of (new in ES6) does use an object-specific iterator and loops over the values generated by that. In your example, the array iterator does yield all the values in the array (ignoring non-index properties).

3 From Microsoft documentation: A jagged array is an array whose elements are arrays. The elements of a jagged array can be of different dimensions and sizes Python documentation about Data Structures. You could store a list inside another list or a dictionary that stores a list. Depending on how deep your arrays go, this might … Read more
You don’t need an array of const objects. A pointer-to-const can point to either const or non-const objects; you can create a dynamic array and initialise a Chunk structure from it like this:
You use pointers. Specifically, you use a pointer to an address, and using a standard c library function calls, you ask the operating system to expand the heap to allow you to store what you need to. Now, it might refuse, which you will need to handle. The next question becomes – how do you … Read more
