How to useArray.from() and slice() Method in Javascript
In this approach, we will use the Array.from() method to convert the string into an array of characters, and then use the slice() method to get the last N characters. Finally, we will join the array back into a string.
Example:
function getLastNCharacters(str, n) {
let charArray = Array.from(str);
let newString = charArray.slice(-n).join('');
return newString;
}
let str = "JavaScript is powerful";
let n = 8;
console.log(getLastNCharacters(str, n)); // Output: "powerful"
Output
powerful
