How to use forEach() Method with an Object In Javascript
In this method, we will iterate over each character of the string using the forEach() method. We’ll use an object to store the count of each character.
Example:
let str = "w3wiki";
let result = {};
// Iterate over each character of the string
str.split("").forEach(char => {
// Increment the count of the character in the object
result[char] = (result[char] || 0) + 1;
});
console.log("The occurrence of each letter in the given string is:", result);
Output
The occurrence of each letter in the given string is: { G: 2, e: 4, k: 2, s: 2, f: 1, o: 1, r: 1 }
JavaScript Program to Count the Occurrences of Each Character
This article will demonstrate different approaches for implementing a JavaScript program to count the occurrences of each character in a string. We will be given a string as input and we return the chars used with the number it occurred in that string.
