how to use the maxby function from lodash in javascript

The maxBy function in lodash is a utility function that helps developers find the maximum value of an array of objects or primitives using a given iteratee function.

Here's an example of how to use the maxBy function to find the object with the highest value property in an array of objects:

index.tsx
const { maxBy } = require('lodash');

const objects = [{ 'n': 1, 'value': 10 }, { 'n': 2, 'value': 5 }];

const maxObject = maxBy(objects, function(o) { return o.value; });

console.log(maxObject); // { 'n': 1, 'value': 10 }

In this example, we first import the maxBy function from the lodash library. Then, we declare an array of two objects, each with a n and value property. We use the maxBy function to find the object in the array with the highest value property. The second argument of the maxBy function is a function that takes an object as an argument and returns the value that the function should use to determine the maximum value. In this case, we simply return the value property of the object.

Finally, we log the resulting object with the highest value property to the console.
