Lambda Functions
Lambda functions, also known as anonymous functions, are small, inline functions defined without a name, typically used for short, simple operations. They are a core feature in functional programming and are supported in many programming languages, allowing developers to write concise code for tasks like mapping, filtering, or sorting data. In cloud computing, AWS Lambda refers to a serverless computing service that runs code in response to events without managing servers.
Developers should learn lambda functions to write more expressive and efficient code, especially in functional programming contexts where they simplify operations on collections and enable higher-order functions. In cloud development, AWS Lambda is essential for building scalable, event-driven applications, such as processing file uploads, handling API requests, or automating tasks, as it reduces infrastructure management overhead and costs.
