As we all know there are more than one way of doing the same thing in the Ruby. Thus, it becomes more important to choose the right way so that it does not affect your Performance
Now, let us discuss about Arrays in Ruby.
=> Array is collection of entities
=> Array can be the collection of different type of objects like, integers, strings, hashes, symbols etc.
=> Methods: There are many inbuilt methods that come in handy for doing particular task
=> One can create Array and get list of the methods that can be called on Array object in Ruby by following command,
Creating Empty Array
Listing Methods on Array
=> Explore the various methods on Array class.
=> You can refer documentation of Ruby Array here.
Array Push and Array Insert
=> We can insert an element is Array by,
=> We can also push element in the Array by,
Both of the methods look exactly same and ultimately they achieve the same result of pushing/inserting an element in the array. But, the difference is
=> Array.push can be used to insert more than one element in Array at a time. e.g.
=> Insertion operator («) can be used to insert only one element at a time in the Array.
If we consider performance, then
Case: Want to add single element in the Array => Prefer using Insertion Operator(«) than using Array.push method. Benchmarking proves the Fact.
Case: Want to add multiple elements in Array => You can prefer Array.push method.
That was all regarding Array Push and Insert, play with methods of Array object to get familiar with. We will get to know about Benchmarking in our upcoming post.
