/**
|
|
* Finds the element in an array that has the maximum value when applying
|
|
* the `iteratee` to each element.
|
|
*
|
|
* @template T - The type of elements in the array.
|
|
* @param {ArrayLike<T> | null | undefined} items The array of elements to search.
|
|
* @param {ValueIteratee<T>} iteratee
|
|
* The criteria used to determine the maximum value.
|
|
* - If a **function** is provided, it extracts a numeric value from each element.
|
|
* - If a **string** is provided, it is treated as a key to extract values from the objects.
|
|
* - If a **[key, value]** pair is provided, it matches elements with the specified key-value pair.
|
|
* - If an **object** is provided, it matches elements that contain the specified properties.
|
|
* @returns {T | undefined} The element with the maximum value as determined by the `iteratee`.
|
|
* @example
|
|
* maxBy([{ a: 1 }, { a: 2 }, { a: 3 }], x => x.a); // Returns: { a: 3 }
|
|
* maxBy([], x => x.a); // Returns: undefined
|
|
* maxBy(
|
|
* [
|
|
* { name: 'john', age: 30 },
|
|
* { name: 'jane', age: 28 },
|
|
* { name: 'joe', age: 26 },
|
|
* ],
|
|
* x => x.age
|
|
* ); // Returns: { name: 'john', age: 30 }
|
|
* maxBy([{ a: 1 }, { a: 2 }], 'a'); // Returns: { a: 2 }
|
|
* maxBy([{ a: 1 }, { a: 2 }], ['a', 1]); // Returns: { a: 1 }
|
|
* maxBy([{ a: 1 }, { a: 2 }], { a: 1 }); // Returns: { a: 1 }
