Use Object.keys and array.map:

var obj = {5.0: 10, 28.0: 14, 3.0: 6}

var arr = Object.keys(obj).map(key => ({type: key, value: obj[key]}));

console.log(arr);

And if your browser supports Object.entries, you can use it:

var obj = {5.0: 10, 28.0: 14, 3.0: 6}

var arr = Object.entries(obj).map(([type, value]) => ({type, value}));

console.log(arr);

Get the keys via Object.keys and then use map function to get the desired output.

const obj = {5.0: 10, 28.0: 14, 3.0: 6};

const mapped = Object.keys(obj).map(key => ({type: key, value: obj[key]}));

console.log(mapped);

Another solution can be provided via Object.entries and array destructuring.

const obj = {5.0: 10, 28.0: 14, 3.0: 6};

const mapped = Object.entries(obj).map(([type, value]) => ({type, value}));

console.log(mapped);
