How to remove the last character from string in Javascript

Using slice()

The easiest way to remove the last character of a string in JavaScript is by using slice method

const name = 'Robert'

console.log(name.slice(0, -1)) // Robert

The slice method returns a new string that contains the extracted portion of the original string, so it does not mutate, modify the original string (in our case const name will remain unchanged no matter how many times we run name.slice(0, -1) method)

Using substring()

const fruit = 'Banana'

console.log(fruit.substring(0, fruit.length - 1)) // Banana
