How to convert array of Object into key/value pair typescript

Currently I'm getting data in the format below:

arr=[
       0: {abc:1},
       1: {efg:2},
       2: {hij:3}
    ]

I need it in below format:

arr=[
      {name:'abc', value:1},
      {name:'efg', value:2},
      {name:'hij', value:3}]

var arr = [  {abc:1}, {efg:2},{hij:3}],
var arr1=[];

      _.forEach(arr, function (val, key) {
        _.forIn(val, function (val, key) {
          arr1.push({ name: key, value: val });
        })
      });
    console.log(arr1);

    });**Implemented using loadash**

Assuming an arr has a following structure, it's only a matter of mapping through it and separating key and value: 

var arr = [ 
    {abc:1},
    {efg:2},
    {hij:3}
]

var result = arr.map(o => {
    var k = Object.keys(o)[0];
    return {
        name: k,
        value: o[k]
    };
});

console.log(result);
