JavaScript - Remove all Occurrences of a Character in JS String Last Updated : 21 Nov, 2024 Comments Improve Suggest changes Like Article Like Report These are the following ways to remove all occurrence of a character from a given string: 1. Using Regular ExpressionUsing a regular expression, we create a pattern to match all occurrences of a specific character in a string and replace them with an empty string, effectively removing that character. JavaScript let str = "Geeks-for-Geeks"; let ch = "-"; let regex = new RegExp(ch, 'g'); let res = str.replace(regex, ''); console.log(res); OutputGeeksforGeeks 2. Using the split() and join() Methods In this approach, Using the split() method, we break a string into an array at each occurrence of a specified character. Then, with the join method, we reconstruct the array into a new string, effectively removing that character. JavaScript let str = "Geeks-for-Geeks"; let ch = "e"; let res = str.split(ch).join(''); console.log(res); OutputGks-for-Gks 3. Using for..in loopThe for...in loop iterates through characters of the input string. If a character doesn't match the specified one, it's appended to a new string, effectively removing the specified character. JavaScript let str = "Geeks"; let ch = "e"; let res = ''; for (let idx in str) { if (str[idx] !== ch) { res += str[idx]; } } console.log(res); OutputGks 4. Using String.prototype.replace() MethodUsing String.prototype.replace() with a function involves passing a regular expression to match the character to be removed globally. Inside the replace function, return an empty string to remove each occurrence of the character. JavaScript let str = "Geeks"; let ch = "e"; let res = str.replace(new RegExp(ch, 'g'), () => ''); console.log(res); OutputGks 5. Using Array.prototype.filter() MethodThe input string is converted into an array of characters using the split('') method. Then, the filter() method is used to create a new array excluding the specified character. Finally, the join('') method is used to reconstruct the array back into a string. JavaScript let str = "Geeks"; let ch = "e"; let res = str.split('').filter(c => c !== ch).join(''); console.log(res); OutputGks Comment More infoAdvertise with us Next Article JavaScript - Remove all Occurrences of a Character in JS String P parzival_op Follow Improve Article Tags : JavaScript Web Technologies javascript-string JavaScript-DSA JavaScript-Program +1 More Similar Reads Non-linear Components In electrical circuits, Non-linear Components are electronic devices that need an external power source to operate actively.
