COPY

Invierte el string que se le pasa. Ejemplo: hola => aloh ---- MÉTODO .SPLIT .split('') Convierte el string dado en un array nuevo. (Para poder usar el método reverse) MÉTODO .REVERSE .reverse() Cambia el orden interno de los array, poniéndolos al revés. Este método solo se puede usar con Arrays y no con Strings. Método .JOIN .join('') Vuelve a convertir el Array en String.

Required Parameters for Functions in JavaScript

 const isRequired = () => { throw new Error('param is required'); };

const hello = (name = isRequired()) => { console.log(`hello ${name}`) };

// These will throw errors
hello();
hello(undefined);

// These will not
hello(null);
hello('David');
The idea here is that it uses default parameters, like how the b parameter here has a default if you don’t send it anything:
function multiply(a, b = 1) {
  return a * b;
}
