Creating a Dynamic Hangman Game with JavaScript: A Technical Overview

Introduction
MTnD Hangman game, a classic word-guessing game, serves as an excellent project to practice and showcase various web development skills. In this project, I developed a Hangman game with enhanced features, including tracking the number of trials, providing clues, displaying trial counts, updating images after failed attempts, and displaying a congratulatory message for correct guesses. The game was deployed on Vercel, allowing for easy sharing and access.

Features

Number of Trials: The game tracks the number of incorrect guesses a player has made. Each incorrect guess reduces the number of remaining trials, adding to the challenge.
Clues: Players can receive clues to help them guess the word. This feature adds a layer of strategy and assistance, making the game more engaging, enhancing the user experience by offering hints when needed. Visual feedback, including changing images and congratulatory messages, was integrated to make the game more engaging and visually appealing.
Displaying the Number of Trials: The number of trials left is displayed prominently, keeping the player informed and adding to the suspense.
Changing Images After Failed Attempts: For each incorrect guess, the game updates an image, typically depicting the progression of the hangman drawing. This visual feedback enhances the player experience by visually representing the consequences of incorrect guesses. 5.Congratulatory Message for Correct Guesses: When the player successfully guesses the word, a congratulatory message is displayed, providing positive reinforcement and a satisfying conclusion to the game.
Game Logic: The core game logic was implemented in JavaScript functions, handling tasks such as validating guesses, updating the state, and determining win/loss conditions.
Deployment: Once the game was complete and thoroughly tested, it was deployed on Vercel. The deployment process involved pushing the code to a Git repository and connecting it to Vercel, which handled the rest of the deployment seamlessly. 8.Audios were added to indicate wrong guesses which makes the game more intriguing, after 5 failed attempts it also returns at sound. After a successful attempt to get the word you get a sound also for success

Technologies Used

HTML: Structure of the game.
CSS: Styling the game interface.
JavaScript used for web interactivity and conditionals. 4.Vercel: The game is deployed on Vercel, a popular platform for deploying front-end projects.Vercel provides a seamless deployment process and ensures the game is accessible from anywhere.

HTML: Structure of the Game
The HTML structure is straightforward, with a few divs and elements to display the game’s components like empty image tags , heading tags and audio tags to be accessible for toggling different game states.

Code Explanation;
I created an object of arrays. The array names serve as the clue to the word. The game is such that it randomly loops into the objects then gets a single array, for example if after it loops and finally gets the languages array. It then randomly loops over the language array and hides the guess. Hence the player only has a clue of what is to be guessed . So if the guessed word is “python”. The player gets to attempt to guess the word. If after 5 failed attempts of guesses, you failed the game and will have to restart. But if you get the word without 5 failed attempts you get a congratulation message.
The addition of images and audio makes the game intriguing making it much more interactive.

Conclusion
Developing this Hangman game was a rewarding experience that allowed me to apply and enhance my skills in JavaScript. The game’s features, including trial tracking, clues, dynamic images, and feedback messages, create an engaging and interactive experience for players. Deploying the game on Vercel ensures it is accessible and shareable, showcasing the capabilities of modern web development tools and practices.

Future Advancement.
I would be looking forward to adding new characteristics to the game in the future to implement.

A score keeper section: it basically stores the amount of success and failures and it returns the total score over 10. For example if you get 6 wrong attempts you get 4/10.
Timer ⌛: I implement a timer, for example for each guess you get 15 seconds if after 5 second you fail to input a word, you automatically get a failed attempt. To improve the difficulty of the game.

Future implementation
The MTnD Hangman game can be used in different niches, only left for me to tailor the objects to your niche, the only things I’ll be needing are keywords that align with your specific niche. The MTnD hangman could be applied in the following;

Educational Hangman: Tailor the game for specific subjects like math, science, or history, where players guess terms related to these topics.
Themed Hangman: Create themes such as movies, books, or famous personalities for each game session.
Multilingual Hangman: Offer versions in different languages to help with language learning.
Custom Word Lists: Allow users to upload or create their own word lists for a personalized experience.
Difficulty Levels: Include options for easy, medium, and hard difficulty levels based on word length or complexity.
Story Mode: Incorporate a storyline or progress system where players unlock new levels or challenges as they succeed.

Each niche could provide a unique twist to the MTnD Hangman game and attract different audiences.
I would be open to suggestions on this project.
