You could map a short hand property.

var array = ["111", "1010", "111", "1010", "1010"],
    result = array.map(branch => ({ branch }));

console.log(result);

You can use map() to create a new array with the results of calling a provided function on every element in the calling array

var arr = [
    "111",
    "1010",
    "111",
    "1010",
    "1010"
]

var res = arr.map(i => ({'branch': i}));
console.log(res);
