We declare the application as HTML5 using the <!DOCTYPE html> declaration.

We load the Maps JavaScript API using a script tag.
These steps are explained below.

map javascript

var kvArray = [["clave1", "valor1"], ["clave2", "valor2"]];

// El constructor por defecto de Map para transforar un Array 2D (clave-valor) en un mapa
var miMapa = new Map(kvArray);

miMapa.get("clave1"); // devuelve "valor1"

// Usando la función Array.from para transformar el mapa a un Array 2D clave-valor.
console.log(Array.from(miMapa)); // Muestra exactamente el mismo Array que kvArray

// O usando los iteradores de claves o valores y convirtiendo a array.
console.log(Array.from(miMapa.keys())); // Muestra ["clave1", "clave2"]
