Description

Cree una función que examine una matriz de objetos (primer argumento) y devuelva una matriz de todos los objetos que tengan pares de nombre y valor coincidentes (segundo argumento). Cada par de nombre y valor del objeto de origen debe estar presente en el objeto de la colección si se va a incluir en la matriz devuelta. Por ejemplo, si el primer argumento es [{ first: "Romeo", last: "Montague" }, { first: "Mercutio", last: null }, { first: "Tybalt", last: "Capulet" }] , y el segundo argumento es { last: "Capulet" } , luego debe devolver el tercer objeto de la matriz (el primer argumento), porque contiene el nombre y su valor, que se pasó como el segundo argumento. Recuerda usar Read-Search-Ask si te atascas. Escribe tu propio código.
