The most common way is simply to use the function name followed by parentheses. If you have a function stored in a variable, you can call it by using the variable name followed by parentheses. You can also call functions using the apply() or call() methods.

Function Call Methods

You can invoke or call a function in two ways: call by value and call by function.

 

Call By Value:

In this calling method, you only pass the copies of the variable and not the actual argument to the function. As the copies of the variable or arguments are being passed, any changes made to the variable in the function don’t affect the actual argument. 

Call By Reference:

In this calling technique, you pass the address or reference of the argument, and the function receives the memory address of the argument. In this case, the actual value of the variable changes, or you can say that it reflects the changes back to the actual variable.
