The array would be the following:

const array_A = ['H',1,'o',2,'l',3,'a']

and what I want to achieve is to see this '6 Hello'.

You can do it like this:

const array_A = ['H',1,'o',2,'l',3,'a']
var palabra = "";
var suma = 0;

array_A.forEach(function(caracter) {
  if (isNaN(caracter)) {
    palabra += caracter;
  } else {
    suma += caracter;
  }
});
console.log(suma, palabra);

here I leave you how it would be done with some functional programming (filter, reduce) and string interpolation (ES6) in case you want to try ...

const array_A = ['H',1,'o',2,'l',3,'a']

let str = array_A.filter(item => typeof item === 'string').join('');
let num = array_A.filter(item => typeof item === 'number');
let sumNum = num.reduce((acc, val) => acc + val);
console.log('${sumNum} ${str}');
