Basic Algorithm Scripting: Reverse a String

Reverse the provided string.

You may need to turn the string into an array before you can reverse it.

Your result must be a string.

Remember to use Read-Search-Ask if you get stuck. Write your own code.

Here i first split the string so as it will read: "j r p e r i o d" The reverse the string: "d o i r e p r j" the join the revered string: "doireprj"

ES6: Create Strings using Template Literals

ES6: Create Strings using Template Literals
A new feature of ES6 is the template literal. This is a special type of string that makes creating complex strings easier.

Template literals allow you to create multi-line strings and to use string interpolation features to create strings.

Consider the code below:

const person = {
  name: "Zodiac Hasbro",
  age: 56
};

// Template literal with multi-line and string interpolation
const greeting = `Hello, my name is ${person.name}!
I am ${person.age} years old.`;

console.log(greeting); // prints
// Hello, my name is Zodiac Hasbro!
// I am 56 years old.
A lot of things happened there.

Firstly, the example uses backticks (`), not quotes (' or "), to wrap the string.

Secondly, notice that the string is multi-line, both in the code and the output. This saves inserting \n within strings.

The ${variable} syntax used above is a placeholder. Basically, you won't have to use concatenation with the + operator anymore. To add variables to strings, you just drop the variable in a template string and wrap it with ${ and }. Similarly, you can include other expressions in your string literal, for example ${a + b}.

This new way of creating strings gives you more flexibility to create robust strings.


Use template literal syntax with backticks to display each entry of the result object's failure array. Each entry should be wrapped inside an li element with the class attribute text-warning, and listed within the resultDisplayArray.

Caesars Cipher

One of the simplest and most widely known ciphers is a Caesar cipher, also known as a shift cipher. In a shift cipher the meanings of the letters are shifted by some set amount.

A common modern use is the ROT13 cipher, where the values of the letters are shifted by 13 places. Thus 'A' ↔ 'N', 'B' ↔ 'O' and so on.

Write a function which takes a ROT13 encoded string as input and returns a decoded string.

All letters will be uppercase. Do not transform any non-alphabetic character (i.e. spaces, punctuation), but do pass them on.

Truncate a string

Truncate a string

---

Truncate a string (first argument) if it is longer than the given maximum string length (second argument). Return the truncated string with a ... ending.
