I'm trying to figure out how to retrieve or access the values stored in a hash. I know hashes store key-value pairs, but I'm not sure how to actually get to those values. How do you access hash values?

To retrieve a value from a hash, the programmer first specifies the hash name. Following this, they enclose the desired key within square brackets, which serves as a signal to Ruby that a value lookup is being requested.

The square bracket syntax not only simplifies the retrieval process but also enhances code readability. It makes it immediately apparent to anyone reviewing the code that a hash is being queried for a specific value.

Ruby, a versatile programming language, offers a unique approach to storing and retrieving data in the form of hashes. These hashes, akin to dictionaries in other programming contexts, enable efficient mapping of keys to their corresponding values.

Accessing values within a hash in Ruby is a straightforward process that leverages bracket notation. This notation, though simple, provides a powerful way to retrieve information based on a given key.
