Function Parameters are the names that are define in the function definition and real values passed to the function in function definition are known as arguments.
You just need to remove the parenthesis: addContact(entityId, refreshContactList); This then passes the function without executing it first. Based on the question, the callback doesn’t accept parameters, which is why I have left them out of the example.
Can a function be a parameter?
A function can take parameters which are just values you supply to the function so that the function can do something utilising those values. These parameters are just like variables except that the values of these variables are defined when we call the function and are not assigned values within the function itself.
Is it possible to use another function as parameter?
You cannot pass function to another function as parameter. Using function pointer you can store reference of a function and can pass it to another function as normal pointer variable. And finally in the function you can call function pointer as normal functions.
Does a function need a parameter?
Parameters are essential to functions, because otherwise you can’t give the function-machine an input.
What is rest API services?
A REST API (also known as RESTful API) is an application programming interface (API or web API) that conforms to the constraints of REST architectural style and allows for interaction with RESTful web services. REST stands for representational state transfer and was created by computer scientist Roy Fielding.
What are rest parameters?
Rest parameter is an improved way to handle function parameter, allowing us to more easily handle various input as parameters in a function. With the help of a rest parameter a function can be called with any number of arguments, no matter how it was defined.
