Function Data Flow

How function work in JavaScript

 

Here is Default syntax of function:

Steps:

1st: When we call the function with arguments(10,20), both arguments stored in 

parameter (parameter1, parameter2

                                                                👇

2nd: then it stored in function body where it called like we called both parameter with 

return statement

                                                                👇

3rd: when we use return  statement then the operation of parameter (here we sum both parameter)

stored in function name(function_name)

                                                                👇

 Final step: when we call or invoke the function name with arguments it shows the function body operation with arguments finally in console

 

                                                         1st Step 🔁Final step

Now you can store the return operation in a variable and then print it in Console

 👉Now call this above function with arguments(10,20)

 then- store sum operation of function body that 

 we pass with return statement --finally stored in 

 in function name and now we can call it when we need

                                                     or

👉Store function body operation(here sum operation) in a variable then return it with return 

statement in function_name
