Are we looking at a declaration of an arrow function? Is this concept even real?

I have been exploring the concept of function expressions versus function declarations with arrow functions.

From my understanding, this is an example of an arrow function expression:

const fred = greeting = () => {
  console.log("Hello from arrow function expression");
};

On the other hand, I believe this is an arrow function declaration:

 anna = () => {
  console.log("Hello from arrow function declaration");
};

Would my assumptions be accurate? Or is there no such thing as an arrow function declaration? Could it be that only arrow function expressions exist?

If that's the case, what do you call it when a named arrow function expression is assigned to another variable?

Excited to hear any insights! :)

Negative.

In JavaScript, there are different ways to define functions such as function declarations, function expressions, and arrow functions (which also fall under the expression category).

(Additionally, there are method definitions that can utilize arrow functions as well.)

ludwig = () => {
  console.log("Greetings from the arrow function declaration");
};

This code snippet demonstrates assigning an arrow function to a variable.

The absence of a variable declaration suggests that it was defined elsewhere, or this could result in an implicit global variable creation, which is not allowed in strict mode.
