+/**
+ * Maps each element of an array based on a provided key-generating function.
+ *
+ * This function takes an array and a function that generates a key from each element. It returns
+ * an object where the keys are the generated keys and the values are the corresponding elements.
+ * If there are multiple elements generating the same key, the last element among them is used
+ * as the value.
+ *
+ * @template T - The type of elements in the array.
+ * @template K - The type of keys.
+ * @param {T[]} arr - The array of elements to be mapped.
+ * @param {(item: T, index: number, array: readonly T[]) => K} getKeyFromItem - A function that generates a key from an element, its index, and the array.
+ * @returns {Record<K, T>} An object where keys are mapped to each element of an array.
+ *
+ * @example
+ * const array = [
+ *   { category: 'fruit', name: 'apple' },
+ *   { category: 'fruit', name: 'banana' },
+ *   { category: 'vegetable', name: 'carrot' }
+ * ];
+ * const result = keyBy(array, item => item.category);
+ * // result will be:
+ * // {
+ * //   fruit: { category: 'fruit', name: 'banana' },
+ * //   vegetable: { category: 'vegetable', name: 'carrot' }
+ * // }
+ *
+ * @example
+ * // Using index parameter
+ * const items = ['a', 'b', 'c'];
+ * const result = keyBy(items, (item, index) => index);
+ * // result will be: { 0: 'a', 1: 'b', 2: 'c' }
