Useful Functions in CodeCraft

In this chapter we'll develop two very useful functions in CodeCraft:

• to build a block: block_m(x, y, z, m)
• to build a column: column_m(x, z, h, m)

We'll use these two functions a lot later in this book:

• to demonstrate the application of JavaScript basic knowledge.

• to construct complicated structures with the JS basics.

• to learn about advanced topics such as time delay, recursion, class/object( Object Oriented Programming), events/callback functions...
