 * Computes the sum of the values that are returned by the `iteratee` function.

 * @template T - The type of the array elements.
 * @param array - The array to iterate over.
 * @param iteratee - The function invoked per iteration.
 * @returns Returns the sum.
 *
 * @example
 * sumBy([1, undefined, 2], value => value); // => 3
 * sumBy(null); // => 0
 * sumBy(undefined); // => 0
 * sumBy([1, 2, 3]); // => 6
 * sumBy([1n, 2n, 3n]); // => 6n
 * sumBy([{ a: "1" }, { a: "2" }], object => object.a); // => "12"
