Grouping Objects by Property in JavaScript Using Object.groupBy

Problem: I needed to group an array of objects by a specific property, such as gender, to categorize them in a structured way.

Solution: Using Object.groupBy() (a proposed JavaScript feature) allows easy grouping of objects in an array based on a provided callback.

const animals = [
  { gender: 'male', name: 'Charlie' },
  { gender: 'female', name: 'Luna' },
  { gender: 'male', name: 'Max' }
];

const groupedAnimals = Object.groupBy(animals, animal => animal.gender);
console.log(groupedAnimals);

// Output:
// {
//   female: [{ gender: 'female', name: 'Luna' }],
//   male: [{ gender: 'male', name: 'Charlie' }, { gender: 'male', name: 'Max' }],
// }
