Array (List) functions in vimscript

Vimscript Arrays are called Lists. They have a set of rules and functions that I'll document here for my own reference:

Basics

• They are defined with let myArray=['one', 'two', 'three']
• They are zero-indexed: echo myArray[0] is one
• They can be accessed from the end echo myArray[-1] is three

Functions

• add(myArray, 'four') adds a new elements. myArray+=['four'] also works
• get(myArray, 0, 'default value') reads a value, with a fallback
• len(myArray) returns 3
• index(myArray, 'three') returns 2 (or -1 if not found)
• join(myArray, '/') returns one/two/three
• split('one/two/three', '/') creates ['one', 'two', 'three']

• List functions
• String functions
