Answer 1

with pure javascript

var myInput = [{ a: 1, b: 2, c: 3 }, { a: 2, b: 4, c: 6 }, { a: 7, b: 8, c: 9 }];
    var myArray = [];
    var myObject = {};
    function isArray(a){
        return Object.prototype.toString.call(a) === '[object Array]' ;
    }
    for (var i = 0; i < myInput.length; i++) {
        for (var key in myInput[i]) {
            if (myInput[i].hasOwnProperty(key)) {
                if (myArray.indexOf(key) === -1) {
                    myArray.push(key);
                    myObject[key] = myInput[i][key];
                } else {
                    if (myObject.hasOwnProperty(key)) {
                        newary = [];
                        if (isArray(myObject[key])) {
                            for (var i = 0; i < myObject[key].length; i++) {
                                newary.push(myObject[key][i]);
                            }
                        } else {
                            newary.push(myObject[key]);
                        }
                        newary.push(myInput[i][key]);
                        myObject[key] = newary;
                    }
                }
            }
        }
    }
    console.log(myObject);
