how to remove last character from string in react js?

Hi Friends 👋,

Welcome To Infinitbility! ❤️

To remove last character from string in react js, just use substring(0, lastindex - 1) method it will return new string based on the provided index so if you pass 0, lastindex - 1 as parameter it returns the string without last index char.

The substring() method returns the part of the string between the start and end indexes, or to the end of the string.

Let’s take an example to remove the last alphabet using the substring() method.

5//  "infinitbilit"
