What is lambda?
A small, anonymous function in programming
lambda explained in plain English
Analogy
A lambda is like a disposable tool that you use once and then throw away, whereas a regular function is like a reusable tool that you keep in your toolbox.
Example
For example, in a web application, a lambda might be used to sort a list of items in response to a user's click on a button.
How is lambda used?
Lambdas are often used in data processing, event handling, and as arguments to higher-order functions.
Common misconceptions about lambda
Some people think that lambdas are only used in functional programming, but they can be used in any type of programming.
History
The term 'lambda' comes from the Greek letter lambda, which was used by mathematician Alonzo Church to represent anonymous functions in his lambda calculus.
