How to Count Character Occurrences in JavaScript - Easy Coding Tutorial!

In this video, I’ll walk you through a simple JavaScript function to count the occurrences of each character in a string. This function, CountCharacter, uses a for loop and an object (hashmap) to tally up characters and output their frequency. Perfect for beginners looking to practice JavaScript basics or enhance problem-solving skills!

👩‍💻 Code Demo: I’ll demonstrate how to use CountCharacter with a sample input ("GIRAFFE") and explain each line, so you’ll fully understand how this function works.

🔹 Topics Covered:

JavaScript loops
Working with objects to store data
Basic string manipulation
Practical function building
✨ Example Output: Using the input "GIRAFFE", the output will show the count of each character, like this: { G: 1, I: 1, R: 1, A: 1, F: 2, E: 1 }
