Find Most Frequent Element in Array | Reduce Method

Описание: In this JavaScript interview tutorial, we solve an important question:
“How do you find the most frequent (repeated) element in an array?”

Using Array.reduce(), we build a frequency counter that tracks how many times each value appears.
This is a powerful and interview-friendly pattern used in data processing, React, and algorithms.

In the example, the number 3 appears the most times, so it becomes the most frequent element.

Perfect for beginners, frontend developers, and coding interviews.
