crea una finción que retorne un valor numérico in javascript

To create a function that returns a numeric value in JavaScript, you can use the return statement.

Here's an example:

function addNumbers(a, b) {
  return a + b;
}

const result = addNumbers(2, 3);
console.log(result); // Output: 5
114 chars
7 lines

In the above example, the addNumbers function accepts two parameters a and b and returns their sum using the return statement.

When you call the addNumbers function with arguments 2 and 3, it returns the numeric value 5, which is then logged to the console using console.log.

You can create any function that returns a numeric value by replacing the body of the function with the appropriate code.
