* Creates a new object composed of the picked object properties.
*
* This function takes an object and an array of keys, and returns a new object that
* includes only the properties corresponding to the specified keys.
*
* @template T - The type of object.
* @template K - The type of keys in object.
* @param obj - The object to pick keys from.
* @param keys - An array of keys to be picked from the object.
* @returns A new object with the specified keys picked.
*
* @example
* const obj = { a: 1, b: 2, c: 3 };
* const result = pick(obj, ['a', 'c']);
* // result will be { a: 1, c: 3 }
