In software development, 'Updating Values in a Ruby Hash' refers to the process of modifying or adjusting the values associated with specific keys in a given hash. A hash is a data structure in Ruby that stores pairs of keys and values. To update a value, you would specify the key and assign a new value to it. If the key doesn't exist, it will be created.
For example, in Ruby, you can update a value in a hash as follows:
hash = { 'key1' => 'value1', 'key2' => 'value2' }hash['key1'] = 'new_value1'
# The hash now looks like this: {'key1' => 'new_value1', 'key2' => 'value2'}
