Add array elements in Ruby

In this article, we will learn how to add elements to an array in Ruby.
Method #1: Using Index

Ruby

# Ruby program to add elements  
# in array 
   
# creating string using [] 
str = ["GFG", "G4G", "Sudo", "Beginner"] 
   
str[4] = "new_ele";
print str
 
# in we skip the elements
str[6] = "test";

Output:

["GFG", "G4G", "Sudo", "Beginner", "new_ele"]

["GFG", "G4G", "Sudo", "Beginner", "new_ele", nil, "test"]

Method #2: Insert at next available index (using push() method) –

Ruby

# Ruby program to add elements  
# in array 
   
# creating string using [] 
str = ["GFG", "G4G", "Sudo", "Beginner"] 
   
str.push("w3wiki")
print str

Output:

 ["GFG", "G4G", "Sudo", "Beginner", "w3wiki"]

Method #3: Using << syntax instead of the push method –

Ruby

# Ruby program to add elements  
# in array 
   
# creating string using [] 
str = ["GFG", "G4G", "Sudo", "Beginner"] 
   
str << "w3wiki"
print str

Output:

 ["GFG", "G4G", "Sudo", "Beginner", "w3wiki"]

Method #4: Add element at the beginning –

Ruby

# Ruby program to add elements  
# in array 
   
# creating string using [] 
str = ["GFG", "G4G", "Sudo", "Beginner"] 
   
str.unshift("ele_1")
print str

Output:

 ["ele_1", "GFG", "G4G", "Sudo", "Beginner"]
