How to delete the last character of a string with JavaScript?
To delete the last character of a string with JavaScript, we can use the string’s replace method.
For instance, we write:
const s = 'foobar'
const newS = s.replace(/(\s+)?.$/, '')
console.log(newS)
to call s.replace with a regex that matches the last character from the string s and replace that with an empty string.
\s matches whitespaces, and . matches any character.
The $ means the end of the string.
As a result, newS is 'fooba'.
