Problem Statement
given a string, get the last character in the string
Solution
to get the last character in the given string, use String charAt() method. charAt() method takes index as argument and returns the character at the index. if we pass (length of the string – 1) for index, then charAt() returns the last character in the string
str.charAt(str.length - 1)
Program
get the last character of the string value in str
let str = 'hello world';
let firstChar = str.charAt(str.length - 1);
console.log(firstChar);
