Ruby | push() function

  • Last Updated : 06 May, 2019

The push() function in Ruby is used to push the given element at the end of the given array and returns the array itself with the pushed elements.

Syntax: push(Elements)

Parameters:
Elements : These are the elements which are to be added at the end of the given array.

Returns: the array of pushed element.

Example 1:






# Initializing some arrays of elements
Array1 = [1, 2, 3, 4]
Array2 = ["a", "b", "c"]
Array3 = ["gfg", "Geeks", "GeeksforGeeks"]
   
# Calling push() function
A = Array1.push(5, 6, 7)                
B = Array2.push("d", "e", "f")               
C = Array3.push("Geek")  
   
# Printing the array of pushed element
puts "#{A}"
puts "#{B}"
puts "#{C}"

Output:

[1, 2, 3, 4, 5, 6, 7]
["a", "b", "c", "d", "e", "f"]
["gfg", "Geeks", "GeeksforGeeks", "Geek"]

Example 2:




# Initializing some arrays of elements
Array1 = [10, 20, 30, 40]
Array2 = ["Z", "Y", "X"]
Array3 = ["ab", "abc", "abcd"]
  
# Initializing some elements 
# which are to be pushed
p = 50, 60
q = "W", "V", "U"
r = "abcde", "abcdef"
  
# Calling push() function
A = Array1.push(p)                
B = Array2.push(q)               
C = Array3.push(r)  
  
# Printing the array of pushed element
puts "#{A}"
puts "#{B}"
puts "#{C}"

Output:

[10, 20, 30, 40, [50, 60]]
["Z", "Y", "X", ["W", "V", "U"]]
["ab", "abc", "abcd", ["abcde", "abcdef"]]

Note: In the above example, it can be seen that if we initialize the parameters
of the function in a separate variable then it gives output as an array inside the array shown above.
