How to Replace Multiple Characters in a String with a Single `replace()` Call in JavaScript?

Replacing Multiple Characters with a Single Replace Call

In JavaScript, you may occasionally encounter the need to replace multiple characters in a string. While chaining multiple replace() calls may suffice for some scenarios, a more efficient and concise approach is leveraging the OR operator (|).

To simultaneously replace multiple characters, you can use the OR operator within the regular expression passed as an argument to the replace() method. For instance, to replace all instances of '_' with a space and '#' with nothing, use the following syntax:

string.replace(/#|_/g, '');

In this expression, the OR operator combines two character classes:

• /#/ matches all occurrences of '#'
• /_/ matches all occurrences of '_'

By placing them inside brackets and separating them with the OR operator, the replace() method will replace any character that matches either pattern.

 Example:

var string = '#Please send_an_information_pack_to_the_following_address:';

string = string.replace(/#|_/g, '');
console.log(string); 

Output:

Please send an information pack to the following address:
