Day 85: Count Value Occurrences in an Object | 100 Days of JavaScript Coding Challenge
🎯 Welcome to Day 85 of the 100 Days of JavaScript Coding Challenge! 🚀
#CodeWithPoonam #100DaysOfCode
📥 Problem Statement:
Write a JavaScript function to count how many times each value appears in an object.
📊 Example:
Input:
{ a: 1, b: 2, c: 1, d: 3, e: 2 }
Output: { 1: 2, 2: 2, 3: 1 }
Input:
{ a: "apple", b: "banana", c: "apple", d: "grape" }
Output: { apple: 2, banana: 1, grape: 1 }
Input:
{ a: true, b: false, c: true, d: true }
Output: { true: 3, false: 1 }
💡 Approach:
✅ Step 1: Extract values using Object.values().
✅ Step 2: Initialize an empty object to store the counts.
✅ Step 3: Use a for...of loop to iterate through the values.
✅ Step 4: Increment the count for each value or initialize it if not present.
✅ Step 5: Return the count object showing the frequency of each value.
📚 Key Concepts Used:
✅ Object.values(): Extracts the values from an object.
✅ for...of: Loops through iterable values.
✅ Counting Logic: Using (count[value] || 0) + 1.
📅 On Day 85, you learned how to count the frequency of values in an object using JavaScript's Object.values() and a for...of loop.
🔥 Keep coding and stay consistent!
