Questions tagged [arguments]

An argument is a value passed to a function, procedure, or command line program. This also refers to the Array-like `arguments` object in JavaScript.

An argument is a value passed to a function, procedure, or program. It is often used interchangeably with the word "parameter", which also has more specific definitions. Usually "argument", or "actual parameter" (as opposed to "formal parameter") is the value of the parameter used within the called routine.

In other words, parameters are used in procedure definitions, and arguments are used in procedure calls.

arguments can also refer to the Array-like object in JavaScript that is available inside functions, this object can be used to access all of the function's arguments regardless of the function's signature.
