How does lodash.mapKeys work?
lodash.mapKeys is a function that creates a new object by applying a mapping function to each key of a source object, while maintaining the same value associated with the key. The mapping function is applied to each key-value pair, and the resulting key-value pairs are used to create a new object.

1 2 3const obj = { a: 1, b: 2, c: 3 }; const mappedObj = _.mapKeys(obj, (value, key) => key.toUpperCase()); console.log(mappedObj); // { A: 1, B: 2, C: 3 }
In this example, lodash.mapKeys is used to map over the keys of an object obj and convert them to uppercase using a mapping function. The resulting object mappedObj has the same values as obj, but with uppercase keys.
