Other methods available are substring() and replace(). substring() does not have negative indexing, so be sure to use str.length - 1 when removing the last character from the string.
let str = 'abc.com';
str.substring(0, str.length - 1); // acb.co
str.substr(0, str.length - 1); // abc.coreplace() takes either a string or a regular expression as its pattern argument.
let str = 'abc.com';
str.replace(/.$/, ''); // abc.coRemove the last character only if the last character is a number. You can use .replace(/\d$/, '') as shown below.
let str = 'abc.io0';
str.replace(/\d$/, ''); // abc.ioDo comment if you have any doubts or suggestions on this Js remove char topic.
