Mi estrategia es eliminar los datos duplicados de la matriz y mostrar los datos que no están duplicados.
const array1 = [{id:1 , name:"John" , age:20}, {id:2 , name:"Sam" , age:15}, {id:3 , name:"Paul" , age:28}, {id:4 , name:"David" , age:50}, {id:1 , name:"John" , age:20}, {id:4 , name:"David" , age:50}] /*Expected result is array1 = [{id:2 , name:"Sam" , age:15}, {id:3 , name:"Paul" , age:28] */Gracias.
