Elixir stands out among programming languages due to its focus on immutability, where variables cannot be changed once they are set. Unlike in Javascript, where mutation can be observed at any time, Elixir’s design ensures that variables remain constant, leading to more understandable and predictable code. Elixir introduces the idea of mutation through function calling and serialized access to state, where changes can only be observed by calling functions. This approach eliminates race conditions and ensures that state changes are controlled and isolated. This unique feature of Elixir allows for more manageable and less surprising programming, especially when scaling applications and handling failures.
