Build an array of arrays from an array using REDUCE in javascript [duplicate]

Question

Input data

const users = [{id: 1, name: 'Madou', age: 37},
  {id: 2, name: 'Fatoumata', age: 33},
  {id: 3, name: 'Amadou', age: 31}];

Output [ [ 1, 'Madou', 37 ], [ 2, 'Fatoumata', 33 ], [ 3, 'Amadou', 31 ] ]

I implemented this:

const _data = users.map((item) => {
  return Object.keys(item).map((value) => item[value]);
});
console.log(_data);

But I want to use REDUCE instead, but I don't have any how to do it

Answer 1

You can use Array.map() as follows:

const users = [{id: 1, name: 'Madou', age: 37},
  {id: 2, name: 'Fatoumata', age: 33},
  {id: 3, name: 'Amadou', age: 31}];
  
const result = users.map(o => Object.values(o));

console.log(result);

Answer 2

const _data = users.reduce((acc, { id, name, age }) => {
  acc.push([id, name, age]);
  return acc;
}, []);
