Dont even go the regular expression route and simply do a straight replace. answered Jun 19, 2019 at 1:46

Not the answer you're looking for? Browse other questions tagged javascript string or ask your own question.Given a string and the task is to remove a character from the given string. Method 1: Using replace() method: The replace method is used to replace a specific character/string with other character/string. It takes two parameters, first is the string to be replaced and the second is the string which is to be replaced with. In this case, the first parameter is the character which is to be removed and the second parameter can be given as an empty string. This will remove the character from the string. This method removes the first occurrence of the string. Syntax: string.replace('characterToReplace', ''); Example: html
Output:
Method 2: Using replace() method with a regular expression: This method is used to remove all occurrences of the specified character, unlike the previous method. A regular expression is used instead of the string along with the global property. It will select every occurrence in the string and it can be removed. Syntax: string.replace(/regExp/g, ''); Example: html
Output:
Method 3: Removing the first or last character using slice() method: The slice() method is used to extract parts of a string between the given parameters. This method takes the starting index and the ending index of the string and returns the string in between these indices. If the ending index is not specified, it is assumed to be the length of the string. The first character could be removed by specifying the beginning index to be 1. It extracts the string from the second character up to the end of the string. The last character could be removed by specifying the ending index to be one less than the length of the string. This extracts the string from the beginning of the string to the second to last character. Syntax: // Removing the first character string.slice(1); // Removing the last character string.slice(0, string.length - 1); Example: html
Output:
Method 4: Removing a particular character at given index using substr() method: This method can be used to remove a character from a particular index in the string. The substr() method is used to extract parts of a string between the given parameters. This method takes two parameters, one is the starting index and the other is the ending index of the string. The string between these indices is returned. The portion of the string before and after the character to be removed is separated and joined together. This removes the character from the specific index. Syntax: string.substr(0, position - 1) + string.substr(position, string.length); Example: html
Output:
