The For example, if a function is passed 3 arguments, you can access them as follows: The
You can use Assigning to indicesEach argument index can also be set or reassigned:
Non-strict functions that only has simple parameters (that is, no rest, default, or destructured parameters) will sync the new value of parameters with the
Non-strict functions that are passed rest,
default, or destructured parameters will not sync new values assigned to parameters in the function body with the
This is the same behavior exhibited by all strict-mode functions, regardless of the type of parameters they are passed. That is, assigning new values to parameters in the body of the function never affects the Note: You cannot write a arguments is an array-like object
For common use cases, using it as an array-like object is sufficient,
since it both is iterable and has
Properties
Reference to the currently executing function that the arguments belong to. Forbidden in strict mode. arguments.length The number of arguments that were passed to the function. arguments[@@iterator] Returns a new
Array iterator object that contains the values for each index in ExamplesDefining a function that concatenates several stringsThis example defines a function that concatenates several strings. The function's only formal argument is a string containing the characters that separate the items to concatenate.
You can pass as many arguments as you like to this function. It returns a string list using each argument in the list:
Defining a function that creates HTML listsThis example defines a function that creates a string containing HTML for a list. The only formal argument for the function is a string that is
You can pass any number of arguments to this function, and it adds each argument as a list item to a list of the type indicated. For example:
Using typeof with argumentsThe
The type of individual arguments can be determined by indexing

Browser compatibilityBCD tables only load in the browser See alsoWhat type of arguments are passed to a function?Positional Arguments
During a function call, values passed through arguments should be in the order of parameters in the function definition. This is called positional arguments.
What are values passed to a function called?The parameter values, called arguments, are passed to the function when the function is called.
What are the arguments given in the function call called?Calling the function involves specifying the function name, followed by the function call operator and any data values the function expects to receive. These values are the arguments for the parameters defined for the function. This process is called passing arguments to the function.
What type of arguments are passed to a function quizlet?An argument is a value passed to a function. A parameter variable is a variable local to the function which receives the argument. That is to say, the argument's value is copied into the parameter variable.
