 #### Problem
 
-An `Atom` is an Elixir basic type whose value is its own name. Atoms are often useful to identify resources or express the state, or result, of an operation. Creating atoms dynamically is not an anti-pattern by itself. However, atoms are not garbage collected by the Erlang Virtual Machine, so values of this type live in memory during a software's entire execution lifetime. The Erlang VM limits the number of atoms that can exist in an application by default to *1_048_576*, which is more than enough to cover all atoms defined in a program, but attempts to serve as an early limit for applications which are "leaking atoms" through dynamic creation.

 For these reasons, creating atoms dynamically can be considered an anti-pattern when the developer has no control over how many atoms will be created during the software execution. This unpredictable scenario can expose the software to unexpected behavior caused by excessive memory usage, or even by reaching the maximum number of *atoms* possible.
