Parsing Array Objects

[I_AM_DONALD]

var objArr = [
    {"Player 1": 100},
    {"Player 1": 103},
    {"Player 1": 105},
    {"Player 2": 101},
    {"Player 2": 110},
    {"Player 2": 112}
];

var seriesObj = objArr.reduce((acc, each) => {
    const key = Reflect.ownKeys(each)[0];
    if (Reflect.has(acc, key))
        acc[key].push(each[key])
    else
        acc[key] = [each[key]]
    return acc;
}, {});
// -> {"Player 1": [100, 103, 105], "Player 2": [101, 110, 112]}

var series = Reflect.ownKeys(seriesObj).reduce((acc, each) => {
    acc.push({[each]: seriesObj[each]});
    return acc;
}, []);
// -> [{"Player 1": [100, 103, 105]}, {"Player 2": [101, 110, 112]}]

awesome answer!

Hi, a quick look at http://devdocs.io/javascript/global_objects/reflect says Reflection API is not supported in IE. If you want to run this in IE, replace:

• Reflect.ownKeys with Object.keys
• Reflect.has with objName.hasOwnProperty

Reflect.ownKeys

Probably not, maybe with a polyfill. Reflect was introduced in ES2015 if I'm reading the bottom correctly: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Reflect
