Function declarations, which declare a variable and assign a function to it, are similar to variable statements, but in addition to hoisting the declaration, they also hoist the assignment – as if the entire statement appeared at the top of the containing function – and thus forward reference is also possible: the location of a function ...
Immediately invoked function expressions may be written in a number of different ways. [3] A common convention is to enclose the function expression – and optionally its invocation operator – with the grouping operator, [4] in parentheses, to tell the parser explicitly to expect an expression.
"Hyperblocks": functions whose natural domain is scalars (text or numbers), extended to accept lists as inputs and apply the underlying function to the scalars in the list or a sublist; Nestable sprites; Codification of Snap! programs to text languages such as Python, JavaScript, C, etc. Metaprogramming, reflection, and macros
Fully written in Python with additional speed ups in Cython. PySide, open source is a Python binding of the cross-platform GUI toolkit Qt developed by The Qt Company, as part of the Qt for Python project. PyQt, open source (GPL and commercial) is another Python binding of the cross-platform GUI toolkit Qt developed by Riverbank Computing.
Ext JS is a JavaScript application framework for building interactive cross-platform web applications [2] using techniques such as Ajax, DHTML and DOM scripting. It can be used as a simple component framework (for example, to create dynamic grids on otherwise static pages) but also as a full framework for building single-page applications (SPAs).
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:
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.
