Defined arrays have the following methods available: .toString ( ) .toLocaleString ( ) .concat ( [ item1 [ , item2 [ , … ] ] ] ) When the concat method is called with zero or more arguments item1, item2, etc., it returns an array containing the array elements of the object followed by the array elements of each argument in order. .join (separator) The elements of the array are converted to Strings, and these Strings are then concatenated, separated by occurrences of the separator. If no separator is provided, a single comma is used as the separator. .pop ( ) The last element of the array is removed from the array and returned. .push ( [ item1 [ , item2 [ , … ] ] ] ) The arguments are appended to the end of the array, in the order in which they appear. The new length of the array is returned as the result of the call." .reverse ( ) The elements of the array are rearranged so as to reverse their order. The object is returned as the result of the call. .shift ( ) The first element o...

At a high level, there are basically three types of data structures.  Stacks  and  Queues  are  array-like  structures that differ only in how items are inserted and removed.  Linked Lists ,  Trees ,   and  Graphs  are structures with  nodes  that keep  references  to other nodes.  Hash Tables  depend on  hash functions  to save and locate data. In terms of complexity , Stacks  and  Queues  are the simplest and can be constructed from  Linked Lists .  Trees  and  Graphs  are the most complex because they extend the concept of a linked list.  Hash Tables  need to utilize these data structures to perform reliably.  In terms of efficiency ,  Linked Lists  are most optimal for  recording  and  storing  of data,  while  Hash Tables  are most performant for  searching ...
