A collection data structure often consisting of a of elements of the same type, each identified by an array index. The simplest type of array is a linear (one-dimensional) array.
Tell a student what an array is in your language, how an array can be manipulated, and ensure they understand where to look for docs on arrays.
- Explain what arrays are in your language? Are the arrays fixed sized or not? Can an array contain elements of different types?
- How to access an array element? What is the syntax for accessing an array element? Where do indexes start from in your language?
- How to create an array? What is the syntax for creating a new array?
- How to add or remove elements from an array? What is the syntax for various manipulations of an array?
This exercise deals with manipulating a stack of playing cards. The reference implementation (JavaScript) teaches:
- Create an array
- Accessing an element from an array
- Changing an element from an array
- Deleting an element from an array
- Adding an element to an array
- Using the length of an array

This exercise deals with analysis on a stack of playing cards. The reference implementation (JavaScript) teaches:
- Find the index of an item in an array
- Find the index of an item matching a predicate in an array
- Test a predicate against all items in an array
- short-circuit on one true (
some) - short-circuit on one false (
every)
- short-circuit on one true (
