Function Declarations

The syntax for creating a function declaration is as follows:

1function functionName(parameter1, parameter2, ...) {
2 // Code to be executed
  • The keyword function indicates the start of a function declaration.
  • functionName is the name assigned to the function. Choose a descriptive and meaningful name that reflects the purpose of the function.
  • Parameters are enclosed within parentheses ( ). They represent the inputs that can be passed to the function.
  • Curly braces { } contain the block of code to be executed when the function is called.



Declare a function named greet with no parameters.


Inside the function body, print the messeage "Hello, John!" to the console.
