most frequent number in a array using javascript

Comment

function findMostFrequentElement(inputArray) {
  if (inputArray.length === 0) {
    return null; // Return null for an empty array
  }

  const frequencyCount = {};
  let mostFrequentElement;
  let maxFrequency = 0;

  for (const num of inputArray) {
    frequencyCount[num] = (frequencyCount[num] || 0) + 1;

    if (frequencyCount[num] > maxFrequency) {
      maxFrequency = frequencyCount[num];
      mostFrequentElement = num;
    }
  }

  return mostFrequentElement;
}

// Test the program
const inputArray = [3, 5, 2, 5, 3, 3, 1, 4, 5];
const mostFrequent = findMostFrequentElement(inputArray);
console.log(mostFrequent); // Output: 3
