In this Article we will go through how to convert an array of objects to a single object only using single line of code in JavaScript.
This is a one-line JavaScript code snippet that uses one of the most popular ES6 features => Arrow Function.
Let's define this short function:
const toObject = (arr, key) => arr.reduce((a, b) => ({ ...a, [b[key]]: b }), {});
toObject(
[
{ id: '1', name: 'Alpha', gender: 'Male' },
{ id: '2', name: 'Bravo', gender: 'Male' },
{ id: '3', name: 'Charlie', gender: 'Female' },
],
'id'
);
/*
{
'1': { id: '1', name: 'Alpha', gender: 'Male' },
'2': { id: '2', name: 'Bravo', gender: 'Male' },
'3': { id: '3', name: 'Charlie', gender: 'Female' },
}
*/
