删除数组中每个字符串的最后一个字符 (JavaScript)

Question

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?

Answer 1

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);

Answer 2

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 });
