Named Arrow Functions in ES2015

In ES2015, arrow functions offer a concise syntax for writing functions. However, unlike traditional named functions, arrow functions do not inherently have a name associated with them.

To provide a name to an arrow function, you can assign it to a variable or property. This allows the function to be referenced by its name after it has been defined.

Example:

Consider the following named function:

function sayHello(name) {
  console.log(name + ' says hello');
}

To convert this function to an arrow function with a name, you can assign it to a variable:

const sayHello = (name) => {
  console.log(name + ' says hello');
};

Now, you can invoke the function using its name:

sayHello('John'); // Output: "John says hello"

It's important to note that the named arrow function is only accessible within the scope in which it was declared. You cannot use the arrow function before it has been assigned to a variable or property.
