How to convert a property inside an array of objects?

Question

I have this: [{id: '1', name: 'name1'},{id: '2', name: 'name2'}...]

I would like to convert the id field to an integer instead of a string. What’s the most elegant way of doing it using loash?

The "most elegant way" is a matter of opinion. What's wrong with the way you're doing it currently? — , Aug 05 '16 at 21:00

Loop over the array with _.forEach() and convert the ID to an integer with parseInt().

_.forEach(yourArray, function(obj) {
    obj.id = parseInt(obj.id, 10);
});

I'm not familiar with lodash but if it's not an issue with your syntax then make a temporary array for storage and use parse int

I know this isn't lodash but you can do this easily in vanilla ES6:

const newArr = oldArr.map(({id, name}) => ({id: Number(id), name});
