Following is a very basic example to merge by keeping both values, however, you can create new object rather mutating existing one. 

let obj1 = { a: 1, b: 2, c: 3 };
let obj2 = { a: 9, d: 8, e: 7 };

Object.entries(obj2).forEach(([key, val]) => {
	obj1[key] = obj1[key] ? [obj1[key], val] : val;
});

console.log(obj1);
