Merges an array recursively and join it as a string with the specified glue character
var stringify = function(arr, glue) {
if (glue == undefined) glue = ',';
var seq = [];
var merge_recursive = function(a) {
// Using BFS algorithm as if it was a tree
for (var i = 0; i < a.length; i++) {
if (Array.isArray(a[i])) {
} else {
return seq;
return merge_recursive(arr).join(glue);
}["hola", ["soy", ["juan", "fernandez"] ], "y", ["no", "tengo", ["dinero"] ] ]));
