Having a variety of data types available to a programmer is beneficial because having various ways to store different types of data is good for both organisation and memory consideration. For example, having a specific data type for the date means that the programmer can correctly allocate a piece of information to the lowest amount of memory it requires. Having multiple types of variable also helps in organisation of the code, as it should be easier to locate a particular piece of information if the programmer knows it is contained in a string for example.
