Whether a hashmap is the same as a dictionary or not depends on the specific programming language you are using. In some languages, they are the same thing, while in others they are different data structures with similar functionality.
In Java, for example, a HashMap is a type of map that stores data in an associative manner using keys and values, whereas a dictionary is not a built-in data type in Java. However, other languages such as Python and Ruby do have a built-in data type called a dictionary that is similar to a HashMap. In these languages, a dictionary is a collection of key-value pairs that is implemented using a hash table, so it has similar performance characteristics to a HashMap.
