#179 Contains Duplicate

You are given an array of integers nums. Write a function that returns true if any value appears more than once in the array. If all elements are unique, return false.

Requirements:

1. The function should take one argument:
   • An array of integers, nums.
2. The function should return:
   • true if there is at least one duplicate value.
   • false if all values are unique.

Example Usage:

// Example 1

const nums1 = [1, 2, 3, 3];
console.log(hasDuplicate(nums1)); // Output: true


// Example 2

const nums2 = [1, 2, 3, 4];
console.log(hasDuplicate(nums2)); // Output: false
