Answer 1

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)
