You can use Object.assign() and spread syntax like this:

const input = [
  { "2019-07-25": { title: "Sub task for 11" } },
  { "2019-07-19": { title: "Sub task for 12" } },
  { "2019-07-24": { title: "Sub task for 13" } }
];

const output = Object.assign({}, ...input)

console.log(output)

You can use reduce to achieve this

var res = [
  { "2019-07-25": { title: "Sub task for 11" } },
  { "2019-07-19": { title: "Sub task for 12" } },
  { "2019-07-24": { title: "Sub task for 13" } }
].reduce((a, b) => ({ ...a, ...b }))
     
console.log(res)
