JavaScript function expressions are a core concept in programming, allowing for the creation of named or anonymous functions. Unlike function declarations, they are not hoisted and must be defined before use. They're key for managing scope, modularity, and can be executed immediately as IIFEs, enhancing code organization and effectiveness. Understanding the differences between function declarations and expressions is essential for any developer looking to write clean, efficient JavaScript code.
