How to remove the last character of a string in JavaScript

Published Apr 20 2020

How can you remove the last character from a string?

The simplest solution is to use the slice() method of the string, passing 2 parameters. THe first is 0, the starting point. The second is the number of items to remove. Passing a negative number will remove starting from the end. This is the solution:

const text = 'abcdef'
const editedText = text.slice(0, -1) //'abcde'

Note that the slice() method does not modify the original string.

It creates a new string, this is why I assign it to a new variable in the above example.
