Explanation:

You can do this with Array#map and destructuring.

Destructuring:

The destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables.

Array#map:

The map() method creates a new array with the results of calling a provided function on every element in the calling array.

Solution:

const data = [["111",1],["1010",4],["111",5],["1010",6],["1010",7]];

const res = data.map(([branch,id])=>({branch,id}));

res.sort((a,b)=>a.id-b.id);

console.log(res);
