  1. A function parameter is a variable used in a function.
  2. Functions need parameters because we need a way to tell the function which variables to use in the function body.

A function can also have variables defined within a function. Function parameters refer to variables that are passed in by the calling function :slight_smile:

@Alko89 You are right, thanks for pointing out.

  1. A function parameter is a variable thatā€™s being passed as an argument to a function for it to be used

  2. Functions might need parameters in order to make it easier to feed them input from the outside - without knowing them ahead of time - and be used in calculations inside the function, making the code more modular, flexible, reusable and efficient

  1. A function parameter is a variable used in a function.

  2. Functions need parameters so that they are able to have flexibility and to operate on different values each time they are called.

What is a function parameter?
An information used by a procedure in the function body. This can help DRY idea
*** Why do functions need parameters?***
The function is an automate and the parameters are the material used to produce the output. Without parameters, the fucntion is less reusable because it works by reference like the object methods getter.

1.a function call provides the value.
2.functions need to interact with parameters to return to caller.

1. What is a function parameter?

a variable used in a function that is initialised with a value provided by the caller of the function

2. Why do functions need parameters?

so that information can be provided to the function by the caller, so the function has data to work with

Why do functions need parameters?

Parameters allow the function to know what to do or what to perform.

1. What is a function parameter?
A function parameter is a variable used in a function these are initialized with a value provided by the caller of the function

2. Why do functions need parameters?
Functions need parameters to allow us to write functions that can perform tasks and return retrieved or calculated results back to the caller

The values are provided by the calling function, not the function itself. :slight_smile:

Who provides value to the function?

A function can work without parameters without errors, it makes them more dynamic because they can be set by somethingā€¦? :wink:

  1. A function parameter is a value within a function, identical to a fixed variable difference being only that the function parameter is set by the function caller
  2. Flexible and efficient solution to pass new data for a function to operate

  1. Parameters are local variables defined in the function.
  2. Functions donā€™t really need parameters, but you can use them to set a default output of the function.

A parameter is a named variable passed into a function. Parameters variables are used to import arguments into a function.
Function parameters are the names listed in the function definition.
Arguments are the values passed to the function.
Parameters are initialized to the values of the arguments supplied.

  1. What is a function parameter? Is a variable used in a function. Function parameters work almost identically to variables defined inside the function, but with one difference: they are always initialized with a value provided by the caller of the function.
  2. Why do functions need parameters? Function parameters are the key mechanisms by which functions can be written in a reusable way, as it allows us to write functions that can perform tasks without knowing what the specific inputs or outputs are ahead of time.

1. What is a function parameter?

  • A function parameter is a variable used within a function. They are initialized when the function is called with copies of the arguments used in the function call.
    2. Why do functions need parameters?
  • Functions need parameters to allow the function to perform a task on data passed to the function.
