How to replace two characters at the same time with js?

Below is my code.

 var str = 'test//123_456';
 var new_str = str .replace(/\//g, '').replace(/_/g, '');
 console.log(new_str);

It will print test123456 on the screen.

My question is how to do it in same regular express? not replace string twice.

Thanks.

Use character class in the regex to match any character in the collection. Although use repetition (+, 1 or more) for replacing // in a single match.

var new_str = str .replace(/[/_]+/g, '');


var str = 'test//123_456';
var new_str = str.replace(/[/_]+/g, '');
console.log(new_str);

FYI : Inside the character class, there is no need to escape the forward slash(in case of Javascript RegExp).

Use the regex to match the list of character by using regex character class.

var str = "test//123_456";
var nstr = str.replace(/[\/_]/g, '');
