I have an array with strings in which I want to remove the last character. How can I make it possible to remove the last character for all strings that I have in the array?
use a .map() to get a new array and for each item do a .slice(0,-1) to remove the last char.
const array = ['abcd', '1234', 'cde', 'dot.']
const withoutLastChar = array.map(string => string.slice(0, -1));
console.log(withoutLastChar);you can used this way
const array = ['ab', 'aabb', 'ba', 'bbaa'];
const removingLastChar = array.map(string => string.substring(0, string.length - 1));
console.log({ removingLastChar });
