How to use Objects In Javascript
In this method, we will create a JavaScript object that will store all the characters and their occurrences to accomplish the task.
Example: In this example, we will store chars and their occurrences in the result object using for loop for iteration.
let str = 'w3wiki'
let result = {}
for(let i = 0;i< str.length;i++){
let ch = str.charAt(i)
if(!result[ch]){
result[ch] =1;
}
else{
result[ch]+=1
}
}
console.log(
"The occurrence of each letter in given string is:",result)
Output
The occurrence of each letter in 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.
