Answer 1

**Sorted Array Object by dotted version value**

    var sampleData = [
      { name: 'Edward', value: '2.1.2' },
      { name: 'Sharpe', value: '2.1.3' },
      { name: 'And', value: '2.2.1' },
      { name: 'The', value: '2.1' },
      { name: 'Magnetic', value: '2.2' },
      { name: 'Zeros', value: '0' },
      { name: 'Zeros', value: '1' }
    ];
    arr = sampleData.map( a => a.value).sort();
    var requireData = [];

    arr.forEach(function(record, index){    
      var findRecord = sampleData.find(arr => arr.value === record);
        if(findRecord){
          requireData.push(findRecord);
        }
      });
    console.log(requireData);

Answer 2

Inspired from the accepted answer, but ECMA5-compatible, and with regular string padding (see my comments on the answer):

function sortCallback(a, b) {

    function padParts(version) {
        return version
            .split('.')
            .map(function (part) {
                return '00000000'.substr(0, 8 - part.length) + part;
            })
            .join('.');
    }

    a = padParts(a);
    b = padParts(b);

    return a.localeCompare(b);
}

Usage:

['1.1', '1.0'].sort(sortCallback);
