In JavaScript, you make a named function like this:

function rank () { return "Captain"; }

A named function is a function declaration if it appears as a statement. For example:

function officer () {
  return rank() + " Reginald Thistleton";
  
  function rank () { return "Captain"; }
}

officer() 

The function rank is defined in the function declaration function rank () { return "Captain"; }. We use the function rank in the statement return rank() + " Reginald Thistleton";. We can deduce two things from this:

  1. Declaring a named function binds the function to the name in its surrounding environment. That’s why we can use the function rank within the function officer. Likewise, officer is declared in the global environment, and that’s why we can use it on the Node command line (or wherever we’re testing this code).

  2. We can declare a named function anywhere and its binding can be used everywhere. That’s why we can declare rank at the bottom of the function, but use it at the top.

That’s a function declaration
