Nodejs Array Remove by Index removeAtIndex(index)

Method Source Code

// A stack and a queue are similar in design, i.e. both can be made from a linked list, but they differ in the way 
// items are accessed by default. A stack gives you the items it contains via last in, first out. A queue gives 
// the items it contains via first in, first out.

// You would a stack to process an execution chain, where the last function on the stack is executed first. You 
// would use a queue when you are processing requests or jobs, where the first job intot he queue is the first 
// job to be processed.
