What is meant by “First Class Function” in JavaScript? According to Wikipedia “In computer science, a programming language is said to have first-class functions if it treats functions as first-class citizens. Specifically, this means the language supports passing functions as arguments to other ...
First-class functions are functions that can be treated like any other value. You can pass them to functions as arguments, return them from functions, and save them in variables. In this episode, we talk about why they are important for functional programming and what features we require of ...
[3] The term was coined by Christopher Strachey in the context of "functions as first-class citizens" in the mid-1960s.[4] First-class functions are a necessity for the functional programming style, in which the use of higher-order functions is a standard practice. A simple example of a...
Passing functions. Since functions are first class citizens in Javascript, we are able to pass them. A common use case as a beginner might be something like this. Lets assume we have some sort of analytics we need to preform on various types of events. You could do something like this. ...

To truly express yourself in JavaScript you needexpressions. Expressions evaluate to values. Youâve already seen a few in passing in our code examples. Take the expression in this statement for instance: If youâve ever taken a math class, balanced your checkbook or done yo...
The rest of the JavaScript uses the GameTest Helper class to actually express the test within asimpleMobTestfunction. Test Functions Test functions are where the actual execution of a test happens. The test function both sets up initial conditions for a test to run, and returns an additional ...
