Proc.new(block) lambda { |args| code } ->(arg1, arg2) { code } object.to_proc { |single_arg| code } do |arg, (key, value)| code end Be careful about operator precedence when you have a line with multiple methods chained, like: str = "abcdefg" puts str.gsub(/./) do |mat...

Not all elements of the XML input will end up as elements of the parsed tree. Currently, this module skips over any XML comments, processing instructions, and document type declarations in the input. Nevertheless, trees built using this module’s API rather than parsing from XML text can have comm...

Node Package Manager (npm) provides following two main functionalities: Online repositories for node.js packages/modules which are searchable on search.nodejs.org. Command line utility to install Node.js packages, do version management and dependency management of Node.js packages. npm <com...

Python provides both builtin methods and external libraries for creating, modifying, parsing, and manipulating dates and times.

There are many situations where it is useful to return several values from a function: for example, if you want to input an item and return the price and number in stock, this functionality could be useful. There are many ways to do this in C++, and most involve the STL. However, if you wish to avoi...

In Node.js, resource intensive operations such as I/O are performed asynchronously, but have a synchronous counterpart (e.g. there exists a fs.readFile and its counterpart is fs.readFileSync). Since Node is single-threaded, you should be careful when using synchronous operations, because they will...

Used to prevent name collisions when using multiple libraries, a namespace is a declarative prefix for functions, classes, types, etc. namespace identifier(opt) { declaration-seq } inline namespace identifier(opt) { declaration-seq } /* since C++11 */ inline(opt) namespace attribute-specifie...

The built-in collections package provides several specialized, flexible collection types that are both high-performance and provide alternatives to the general collection types of dict, list, tuple and set. The module also defines abstract base classes describing different types of collection functi...
