Express validator and req.getValidationResult ()

The Express-Validator module uses a new function: req.getValidationResult () . This function returns an object if there are validation errors. The object looks like this:

{param: "field name", msg: "error message", value: "<field input value>"}

The question is how to return the .msg parameter from the object? When i use

req.getValidationResult().then(function(result){
        if(!result.isEmpty()) {
            console.log(result.array());
            //return;
        } else {
            console.log('Validation Ok');
        }

the function returns an array. But I only need .msg.

The code should be as follows



req.getValidationResult().then(function (result) {
        if (!result.isEmpty()) {
            var errors = result.array().map(function (elem) {
                return elem.msg;
            });
            console.log('There are following validation errors: ' + errors.join('&&'));
            res.render('register', { errors: errors });
        } else {

                response.render('route',{validation:result.array()})

 <% if(validation) {%>
<ul>
    <% for(var i = 0;i< validation.length;i++){ %>
    <li><%= validation[i].msg %></li>
