const parts = ["shoulders", "knees"];

const lyrics = ["head", ...parts, "and", "toes"];

// TOTAL lyrics ["head", "shoulders", "knees", "and", "toes"]

COPY

En este ejemplo, el operador de propagación (…parts) expande los elementos del array parts dentro del nuevo array lyrics. También se utiliza para expandir los elementos del array list en argumentos individuales para algunas funciones. De esta manera, se pueden pasar todos los elementos de la lista como argumentos separados a estas funciones. En resumen, el operador de propagación es útil para expandir y combinar elementos de objetos iterables (arrays, strings, mapas y conjuntos), lo que permite un código más limpio y fácil de leer en muchas situaciones.

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;
}
