Rest parameters are similar to Javascript's arguments object, which is an array-like object that contains all of the parameters (named and unnamed) in the current function call. Unlike arguments, however, rest parameters are true Array objects, so methods such as .slice() and .sort() can be used on them directly.
^c Subranges are used to define the bounds of the array. ^d JavaScript's array are a special kind of object. ^e The DEPENDING ON clause in COBOL does not create a true variable length array and will always allocate the maximum size of the array.

A function definition starts with the name of the type of value that it returns or void to indicate that it does not return a value. This is followed by the function name, formal arguments in parentheses, and body lines in braces. In C++, a function declared in a class (as non-static) is called a member function or method.
To import JavaScript classes, the dependency on TObject as the root of all class types needed to be modified. This allows the user to define a class as external, and classes written in JavaScript that match the interface can thus be created and used alongside those written in Pascal. Anonymous classes can also be used as lightweight objects.
Similarly, a delete expression calls a delete function, also known as a deallocator function, whose name is operator delete. [ 2 ] [ 3 ] Any new expression that uses the placement syntax is a placement new expression, and any operator new or operator delete function that takes more than the mandatory first parameter ( std :: size_t ) is a ...
Jasmine tests can run browser tests by including a simple SpecRunner.html [9] file or by using it as a command line test runner supported for various languages like Nodejs, Python, Ruby, or (old way) by using Karma, [10] a simple JavaScript test runner tool.
A helper function is a function which groups parts of computation by assigning descriptive names and allowing for the reuse of the computations. [6] Although not all wrappers are helper functions, all helper functions are wrappers, and a notable use of helper functions—grouping frequently utilized operations—is in dynamic binary translation, in which helper functions of a particular ...
