  2. Named parameter - Wikipedia

    en.wikipedia.org/wiki/Named_parameter

    A function call using named parameters differs from a regular function call in that the arguments are passed by associating each one with a parameter name, instead of providing an ordered list of arguments. For example, consider this Java or C# method call that doesn't use named parameters:

  3. Callback (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Callback_(computer...

    In the following C code, function print_number uses parameter get_number as a blocking callback. print_number is called with get_answer_to_most_important_question which acts as a callback function. When run the output is: "Value: 42".

  4. Python syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    In all versions of Python, boolean operators treat zero values or empty values such as "", 0, None, 0.0, [], and {} as false, while in general treating non-empty, non-zero values as true. The boolean values True and False were added to the language in Python 2.2.1 as constants (subclassed from 1 and 0 ) and were changed to be full blown ...

  8. Higher-order function - Wikipedia

    en.wikipedia.org/wiki/Higher-order_function

    In mathematics and computer science, a higher-order function (HOF) is a function that does at least one of the following: takes one or more functions as arguments (i.e. a procedural parameter, which is a parameter of a procedure that is itself a procedure), returns a function or value as its result. All other functions are first-order functions.

  9. Async/await - Wikipedia

    en.wikipedia.org/wiki/Async/await

    First, the async keyword indicates to C# that the method is asynchronous, meaning that it may use an arbitrary number of await expressions and will bind the result to a promise. [1]: 165–168 The return type, Task<T>, is C#'s analogue to the concept of a promise, and here is indicated to have a result value of type int.
