How do I get all the values that are inside this foreach and show off it? It only takes the last one when I give ALERT:

var arrayAdicional = item.ingrediente_adicional.forEach(function(ingrediente)
{

 prodadicional = ingrediente.ingrediente.nome;

 return prodadicional;

 })

alert(arrayAdicional);

It seems to me that you want to map the values, and for this there is map that creates a new array with the return of each loop iteration that forEach creates.

You can use this:

var arrayAdicional = [];
item.ingrediente_adicional.forEach(function(ingrediente){

    arrayAdicional.push(ingrediente.ingrediente.nome);
})

console.log(arrayAdicional);

undefined

It seems to me that you want to map the values, and for this there is .map() that creates a new array with the return of each loop iteration that .map() creates.

You can use this:

var arrayAdicional = item.ingrediente_adicional.map(function(ingrediente){
     return ingrediente.ingrediente.nome;    
});

alert(JSON.stringify(arrayAdicional, null, 4))

undefined
