Node.js programs are invoked by running the interpreter node interpreter with a given file, so the first two arguments will be node and the name of the JavaScript source file. It is often useful to extract the rest of the arguments by slicing a sub-array from process.argv .

The input to eval is not necessarily a string; it may be structured representation of code, such as an abstract syntax tree (like Lisp forms), or of special type such as code (as in Python). The analog for a statement is exec , which executes a string (or code in other format) as if it were a statement; in some languages, such as Python, both ...
Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types.

It converts input from standard input into arguments to a command. Some commands such as grep and awk can take input either as command-line arguments or from the standard input.
On the other hand, if the code is defined by the command object itself, the target object will be a different object entirely. Command Object, routed event arguments, event object: the object that is passed from the source to the Command/Action object, to the Target object to the code that does the work.
