You can create, update, delete, edit object and get back a new copy of object.

module.exports = {
    pick: function(object, pickItems){
        let obj = Object.create({});
        Object.keys(object).forEach((key)=>{
            if(pickItems.indexOf(key) != -1){
                obj[key] = object[key];
            }
        });
        return obj;
    },
    remove: function(object, removeItems){
        let obj = Object.create({});
        Object.keys(object).forEach((key)=>{
            if(removeItems.indexOf(key) == -1)
                obj[key] = object[key];
        });
        return obj;
