What is an anonymous function in Go? It is just a normal function without a name. Anonymous functions are also called lambda functions or function literals. They are commonly defined and are being passed around as small, self-contained code blocks. Anonymous functions are often used in Go for simple tasks such as sorting or filtering … Read more Anonymous function in Go: An Easy Guide with 4 Use Cases
defer in Go allows postponing the execution of a function until the surrounding function returns. It’s a powerful mechanism often used for resource management, cleanup, or ensuring specific functions run at the end of a scope. Functions deferred within a scope are executed in reverse order, following a Last-In-First-Out (LIFO) approach. This construct aids in maintaining clean, readable code by separating setup and teardown actions, improving code clarity, and ensuring critical tasks execute before the function exits, contributing to robust and more manageable Go programs.
