+/**
+* Maps each element of an array or an object based on a provided key-generating function.
+*
+* This function takes an array or object and a function that generates a key from each element or value. It returns
+* an object where the keys are the generated keys and the values are the corresponding elements or values.
+* If there are multiple elements or values generating the same key, the last one among them is used
+* as the value.
+*
+* @param collection - The collection to iterate over.
+* @param [iteratee] - The iteratee to transform keys.
+*   - If a function is provided, it's invoked for each element in the collection.
+*   - If a property name (string) is provided, that property of each element is used as the key.
+*   - If a property-value pair (array) is provided, elements with matching property values are used.
+*   - If a partial object is provided, elements with matching properties are used.
+*   - If omitted, the identity function is used.
+* @returns Returns the composed aggregate object.
+*
+* @example
+* // Using an array of objects
+* keyBy([{ id: 'a' }, { id: 'b' }], 'id');
+* // => { a: { id: 'a' }, b: { id: 'b' } }
+*
+* @example
+* // Using a function iteratee
+* keyBy(['a', 'b', 'c'], val => val.toUpperCase());
+* // => { A: 'a', B: 'b', C: 'c' }
