如何连接数组中的两个或多个对象？ Javascript

Question

I want to join two objects that are inside an array:

const test = [{name: ""}, {age: ""}, {nac: ""}];

I need it to look like this:

const test2 = [{name: "", age: "", nac: ""}];

I tried with: Object.assign () but I can't get it.

Any other ideas I can try?

Answer 1

You can use Object.assign with spread syntax .

 const test = [{name: ""}, {age: ""}, {nac: ""}]; const test2 = [Object.assign({}, ...test)]; console.log(test2);

Answer 2

You can use array.prototype.reduce function that will be useful when reducing an array to a single value. I have given example below

const test = [{name: ""}, {age: ""}, {nac: ""}];
const reducer = (accumulator, currentValue) => {
  for (var key in currentValue) {
    accumulator[key] = currentValue[key];
  }
  return accumulator;
};

var finalObj = test.reduce(reducer, {});
console.log(finalObj);
console.log([finalObj]);
