Sequences are ordered groups of objects, there are several primitive types which can be considered sequences, each with their pros and cons.
A sequence is either an array or a list, where an array is either a vector or a string.
This function returns true if object is a sequence.
|• Cons Cells:||An ordered pair of two objects|
|• Lists:||Chains of cons cells|
|• Vectors:||A chunk of memory holding a number of objects|
|• Strings:||Strings are efficiently-stored vectors|
|• Array Functions:||Accessing elements in vectors and strings|
|• Sequence Functions:||These work on any type of sequence|
