Never heard the term Lambda function before. A brief google search indicated that it’s just another word for an arrow function expression: x => x * 2

I learned from CS50 is an anonymous function. That means a function that has no name or identifier.

As per Wikipedia.

Cheers!

Ok, turns out that both our inputs aren’t precise. According to this article, the main feature of a lambda function is that they are passed as data and not hoisted:

In JavaScript, everything can be treated as an object, this means that a function can be sent into another function as a parameter and can also be retrieved from the called function as a return value

That is done mostly in shorthand syntax (fat arrow function) and mostly anonymous, but not necessarily:

The most salient point which differentiates lambda functions from anonymous functions in JavaScript is that lambda functions can be named

a lambda function is not necessarily anonymous and an anonymous function is not necessarily a lambda expression if it is not passed around like data. The fat (or thin) arrow notation is simply syntactic sugar.
