RUBY - JOIN TWO ARRAYS

How to extend an existing Array or join two Arrays?

Let us say, we have a Array that contains three names, Mohan, Kriti and Salim. And we want to insert a new Array with two names Sia and Andrew at the end of the Array.

Well! Two arrays can be joined by using the + operator

Let us see with the below example.

Example :

x = ["Mohan", "Kriti", "Salim"]
y = ["Sia", "Andrew"]
z = x + y
puts z

Output :

Mohan
Kriti
Salim
Sia
Andrew

So, in the above code we have created a Array and initialised to the variable x.

x = ["Mohan", "Kriti", "Salim"]

Below is how the values are positioned in the Array,

Also we have another Array that contains, Sia and Andrew.

	y = ["Sia", "Andrew"]

Next, we have used the + operator to add the the Arrays x and y.

z = x + y

And the Arrays x and yis joined and initialised to a new Array z.

And the new array z looks like,

['Mohan', 'Kriti', 'Salim', 'Sia', 'Andrew']
