How to Get the Last Two Characters of a String in JavaScript

const str = 'Coding Beauty';

const last2 = str.slice(-2);
console.log(last2); // ty

// When we pass a negative number as an argument,
// slice() counts backward from the last string character to find the equivalent index.
// So passing -2 to slice() specifies a start index of str.length - 2.

const last2Again = str.slice(str.length - 2);
console.log(last2Again); // ty

// Note
// We can use substring() in place of slice() to get the first two characters of a string:

const str = 'Coding Beauty';
const last2 = str.substring(str.length - 2);
console.log(last2); // ty

// However, we have to manually calculate the start index ourselves with str.length - 2,
// which makes the code less readable.
// This is because unlike slice(), substring() uses 0 as the start index if a negative number is passed.

const str = 'Coding Beauty';

// -2 is negative, 0 used as start index
const notLast2 = str.substring(-2);

console.log(notLast2); // Coding Beauty

last five characters of string javascript

var hello = "Hello World";
