My solution - Random between 2 numbers

// Collect input from a user
alert("Vamos a generar un número aleatorio entre dos valores dados");
const inputLow = prompt("Ingresa un número natural mayor que 1");
const inputHigh = prompt(`Ingresa un número natural mayor que ${inputLow}`);
// Convert the input to a number
const lowNumber = parseInt(inputLow);
const highNumber = parseInt(inputHigh);

if (highNumber && lowNumber && lowNumber < highNumber) {
  // Use Math.random() and the user's number to generate a random number
  const randNumber = Math.round(Math.random()*(highNumber - lowNumber)) + lowNumber
  // Create a message displaying the random number
  let message = `<h1>Has ingresado el número ${inputLow} y ${inputHigh}</h1> <h2>He creado un número aleatorio entre ${inputLow} y ${inputHigh}</h2><p>El número aleatorio es: ${randNumber}</p>`
  const mainSeletor = document.querySelector('main')
  mainSeletor.innerHTML = message
} else {
  alert("Debes elegir un número entero mayor que 1. Además el primero debe ser menor al segundo. Intenta de nuevo recargando la página");
