Answer 1

One quick way is to use Object.assign and spread operator

 let arr = [{"1":"test1"},{"2":"test2"},{"3":"test3"}] let obj = Object.assign({},...arr); console.log(obj);

Doc: Object.assign , spread operator

Answer 2

 var arr = [{"1":"test1"},{"2":"test2"},{"3":"test3"}]; var newarr = arr.reduce(function(data,val){ Object.assign(data[0],val); return data; },[{}]); console.log(newarr);
