Currying is the process of transforming a function that takes multiple arguments into a sequence of functions that each has only a single parameter. Currying is related to, but not the same as, partial application.
Let's consider the following function in JavaScript:
var add = (x, y) => x + y
...
bindings: {
mandatory: '='
optional: '=?',
foo: '=?bar'
}
Optional attributes should be marked with question mark: =? or =?bar. It is protection for ($compile:nonassign) exception.
In traditional object-oriented languages, x = x + 1 is a simple and legal expression. But in Functional Programming, it's illegal.
Variables don't exist in Functional Programming. Stored values are still called variables only because of history. In fact, they are constants. Once x takes a value, it...
Redis provides three commands to count the items within a sorted set: ZCARD, ZCOUNT, ZLEXCOUNT.
The ZCARD command is the basic test for the cardinality of a set. (It is analogous to the SCARD command for sets.) . ZCARD returns the count of the members of a set.
Executing the following code to add...
As you may have noticed in the example above, we are rewriting the same step multiple times:
Given the user is on the login page
This can be exceptionally tedious, especially if we have more than one given step that is reused. Gherkin provides a solution for this by giving us another keyword to ...
In some cases you may want to rerun the same scenario over and over, substituting out the arguments. In this case, Gherkin provides several new keywords to accommodate this situation, Scenario Outline: and Example:. The Scenario Outline keyword tells Cucumber that the scenario is going to run multip...

A character type is an enumeration that includes a character literal:
type Roman_Numeral is
('I', 'V', 'X', 'L', 'C', 'D', 'M', Unknown);`
These are the “bit fiddling” types. They have logical operators, too, such as xor, and they “wrap around” at the upper bound, to 0 again.
type Bits is mod 2**24;
L : Bits := 2#00001000_01010000_11001100# or 7;
If you're accepting user input for folder paths, you might need to check for trailing backslashes (\) before building a file path. The FSO.BuildPath method makes this simpler:
Const sourceFilePath As String = "C:\Temp" '<-- Without trailing backslash
Const targetFilePath As Strin...
In this example you will explore how to export the following data from Acumatica ERP in batches via the REST Contract-Based API:
stock items existing in the application in batches of 10 records
all sales orders in batches of 100 records
To export stock items in batches of 10 records with mult...
Once using is used to introduce the name cout from the namespace std into the scope of the main function, the std::cout object can be referred to as cout alone.
#include <iostream>
int main() {
using std::cout;
cout << "Hello, world!\n";
}

As a special case, a using-declaration at class scope can refer to the constructors of a direct base class. Those constructors are then inherited by the derived class and can be used to initialize the derived class.
struct Base {
Base(int x, const char* s);
};
struct Derived1 : Base {...
When you're ready to upload your project to the phonegap-build service, zip the content of the www folder and upload the zip file to the phonegap-build service.
It is recommended to only zip the content of the www folder, and not the www folder itself. However, this is just a recommendation and zip...
