Lambda

Lambda, in computing, refers to anonymous functions—small, inline functions without a name that can be passed as arguments or returned from other functions. They are a core feature in functional programming and are widely supported in languages like Python, JavaScript, Java, and C#. Lambdas enable concise, on-the-fly operations such as mapping, filtering, or sorting data.

Also known as: Lambda functions, Anonymous functions, Closures, Arrow functions, λ functions

Why learn Lambda?

Developers should learn lambdas to write more expressive and efficient code, especially for data processing tasks like list comprehensions, event handling, or functional transformations. They are essential in modern programming for simplifying code, reducing boilerplate, and enabling functional paradigms in multi-paradigm languages.
