    Use toLocaleDateStringwith esas local and replacewith regular expressions to make the fine adjustments since using only toLocaleDateStringthe result would be14 feb. 2017

    Example:

    var opciones = { year: 'numeric', month: 'short', day: 'numeric' };
var fecha = new Date()
  .toLocaleDateString('es',opciones)
  .replace(/ /g,'-')
  .replace('.','')
  .replace(/-([a-z])/, function (x) {return '-' + x[1].toUpperCase()});
console.log(fecha);

  2. I add this answer for users who prefer to use the moment.js library , very popular when handling dates.

    The details of the output format can be seen here

    //Usamos el idioma español
moment.locale('es');
let now= moment();

//formato por defecto
console.log(now)

//formato predefinido, hay más opciones (ver enlace anterior)
console.log(now.format('LL'));

//formato pedido por el OP (los meses en español empiezan por minúscula)
console.log(now.format('DD-MMM-YYYY'));
    <script src="https://momentjs.com/downloads/moment-with-locales.min.js"></script>

  3. With information from here :

    const date = new Date()
const options = {
  year: 'numeric', month: 'numeric', day: 'numeric',
  hour: 'numeric', minute: 'numeric', second: 'numeric',
  hour12: true,
  timeZone: 'America/Mexico_City' 
};
console.log(new Intl.DateTimeFormat('es-MX', options).format(date));

//imprimió:
//"13/5/2020 10:09:50 p. m."
