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()
andjoin()
- 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);
Approach 2: Using split()
and join()
The split() method helps us convert a string into an array of characters, and then join() can be used to create a new string without the specified character.
Here is an example of Here’s how you can remove a specific character using split and join:
// 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.
Here’s an example, of removing a character from the string at the index using a for loop:
// 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);
Conclusion
