You appear to be taking on a lot of learning at once, not a bad thing, but it can be frustrating ;)

Try the following: Data: Arrays come back to us if there are elements of this you don't understand

In essence an array is a variable and a list is a literal, but read the documentation for greater detail and genuine understanding, you need to gain genuine understanding of the basics to progress your learning

Update:Added shortcut to online documentation

An array is a variable that can hold a variable number of scalars.

List can refer to many things.

• A list is values on the stack.
• A series of comma delimited items is also known as a list literal.
• Named operators (i.e. those in perlfunc) are also called list operators in the documentation.
• The comma operator is actually called the list operator internally.
