To iterate over values in a hash in Ruby, you can use the each_value method or a for loop. This allows you to access each value in the hash.
We can iterate over values in a hash in Ruby using the each_value method, which provides a convenient syntax for iterating over all values in the hash.
For example,
my_map
with some key-value pairs. In this example, the hash has string keys and integer values.each_value
method to iterate over the values in the hash.each_value
, we access each value.puts
function to verify that we are iterating over all values.my_map = {
'one' => 1,
'two' => 2,
'three' => 3
}
# Iterate over values using each_value method
my_map.each_value do |value|
puts value
end

We can iterate over values in a hash in Ruby using a for loop with the values method, which provides a flexible way to access each value in the hash.
For example,
my_map
with some key-value pairs. In this example, the hash has string keys and integer values.values
method to get an array of the values in the hash.puts
function to verify that we are iterating over all values.my_map = {
'one' => 1,
'two' => 2,
'three' => 3
}
# Iterate over values using for loop
for value in my_map.values do
puts value
end

We can store values in a separate array and then iterate over the array in Ruby, which provides a way to work with values independently of their keys.
For example,
my_map
with some key-value pairs. In this example, the hash has string keys and integer values.values
to store the values from the hash.values
method to get an array of the values in the hash and store it in the values
array.values
array and print each value to the console using the puts
function to verify that we have stored all values separately.my_map = {
'one' => 1,
'two' => 2,
'three' => 3
}
# Store values in a separate array
values = my_map.values
# Iterate over the values array
for value in values do
puts value
end
