ES6 - Fecha
los Date objectes un tipo de datos integrado en el lenguaje JavaScript. Los objetos de fecha se crean con el nuevoDate () como se muestra en la siguiente sintaxis.
Una vez que se crea un objeto Date, varios métodos le permiten operar en él. La mayoría de los métodos simplemente le permiten obtener y establecer los campos de año, mes, día, hora, minuto, segundo y milisegundo del objeto, utilizando la hora local o la hora UTC (universal o GMT).
El estándar ECMAScript requiere que el objeto Date pueda representar cualquier fecha y hora, con una precisión de milisegundos, dentro de los 100 millones de días antes o después del 1/1/1970. Este es un rango de más o menos 273,785 años, por lo que JavaScript puede representar la fecha y la hora hasta el año 275755.
Puede usar cualquiera de las siguientes sintaxis para crear un objeto Date usando Date () constructor.
new Date( )
new Date(milliseconds)
new Date(datestring)
new Date(year,month,date[,hour,minute,second,millisecond ])Note - Los parámetros entre paréntesis son siempre opcionales.
