mapValues
Creates a new object with the same keys as the given object, but with values generated by running each own enumerable property of the object through the iteratee function.
Signature
function mapValues<T extends Record<PropertyKey, unknown>, K extends keyof T, V>(
object: T,
getNewValue: (value: T[K], key: K, object: T) => V
): Record<K, V>;
Parameters
obj(T extends Record<PropertyKey, unknown>): The object to iterate over.getNewValue: ((value: T[K], key: K, object: T) => V): The function invoked per own enumerable property.
Returns
(Record<K, V>): The new mapped object.
Examples
const obj = { a: 1, b: 2 };
const result = mapValues(obj, value => value * 2);
console.log(result); // { a: 2, b: 4 }
