Working with Immutable Data

Explore the concept of immutable data in functional programming and how Elixir handles data without mutation. Understand how immutability removes the need for locks in concurrent code, enables safe parallelism, and improves program clarity. Discover Elixir's efficient data reuse and compare it to mutability in other languages.

Data in functional programming

Conventional languages use mutating shared values that require thread and lock mechanisms to work with concurrency and parallelism. In functional programming, all values created in the program are immutable. By default, each function will have a stable value. That means lock mechanisms are ...
