How to Remove a Specific Character from String in JavaScript

Here are multiple approaches to remove specific characters from a string in javascript by w3school:

• Approach 1: Using replace()
• Approach 2: Using split() and join()
• Approach 3: Remove a specific character from the string using for loop in JavaScript

Approach 1: Using replace()

The replace() method in js helps us to replace a specific character with another character or to remove it from an empty string.

Here’s how you can remove a specific character using replace():

// provided string
let myGivenString = "Hello, World!";

// Remove the comma (,) from the string using replace
let removeSpecificCharStr = myGivenString.replace(/,/g, '');

console.log("Original String:", myGivenString);
console.log("Remove Specific Character from String (Remove comma):", removeSpecificCharStr);

// Given string
let myStr = "Hello, World!";

// Remove the comma (,) from the string using split and join
let RemoveSpecificCharStr = myStr.split(',').join('');

console.log("Original String:", myStr);
console.log("Modified String (Remove comma):", RemoveSpecificCharStr);

Approach 3: Remove a specific character from the string using for loop in JavaScript

For loop helps us to iterate through each character of the string and create a new string by removing the specified character.

// Sample string
let sampleString = "Hello, World!";
let charToRemove = ',';

// Remove the specified character from the string using a loop
let removeCharString = '';
for (let i = 0; i < sampleString.length; i++) {
  if (sampleString[i] !== charToRemove) {
    removeCharString += sampleString[i];
  }
}

console.log("Original String:", sampleString);
console.log("Modified String (Remove specified character):", removeCharString);
