Best Javascript Games: Javascript Explained

Table of Contents

When it comes to creating browser-based games, Javascript is a powerful, versatile and accessible language. As the most popular scripting language for browsers, Javascript offers developers a platform for taking advantage of HTML5 technologies to create exceptional gaming experiences. Here, we explore the basics of Javascript and the top 10 Javascript games, as well as the tools, libraries and tips available to developers.

What is Javascript and Why Is It Used For Games?

Javascript is an interpreted, object-oriented scripting language designed to work in web browsers. It was initially designed by Brendan Eich in 1995 as a lightweight scripting language to add scripting capabilities to web browsers. It is now used extensively across the internet and is the third most used language in the world.

Javascript is well-suited for game development because of its integration with HTML and the DOM, dynamic capabilities, speed, and access to browser functionality such as 3D graphics. It is also easily integrated with third-party libraries and frameworks, making it easier to create rich, complex experiences with relatively little coding effort. Javascript games are also popular because they’re easily deployed and can reach a large audience without the need for additional downloads.

Top 10 Javascript Games

The popularity of browser-based games has grown rapidly since the introduction of HTML5 and other modern technologies. There are now many high-quality games developed with Javascript. Here are 10 of the best:

  • Inferno – Developed by the Mozilla Creative team, Inferno is a fast-paced platform game set within a procedurally generated 3D landscape.
  • Flappy Bird – This cult classic is a tribute to classic side-scrollers. Tough but addictive, it’s a true test of your concentration and reflexes.
  • Bubble Tanks Tower Defense – While this tower defense game isn’t visually impressive, the tactical gameplay more than makes up for it. You’ll need good strategic skills to survive wave after wave of tank battles.
  • – This simple but addictive game has been taken over the internet. Control your blob and absorb others to become the biggest in the game.
  • ARK: Survival Evolved – This open-world RPG offers an immersive experience with great graphics and sound, as well as multiple levels of difficulty.
  • Runescape – The classic MMORPG has evolved over time and now features improved graphics, new features and content.
  • Candy Crush Saga – Developed by, this match-3 puzzler has been a global success. Swap candy pieces to match them and score points.
  • Spelunky – This roguelike platformer is incredibly fun and challenging. Jump, dash and fight your way through randomized levels.
  • BombSquad – Enjoy explosive arcade combat with up to 8 players. Unlock custom characters, weapons and levels.
  • – Race against other players or AI opponents in this fast-paced Snake-style game.

Benefits of Developing with Javascript

In addition to great performance and ease of development, Javascript also offers some unique advantages when it comes to game development:

  • Cross-platform compatibility: As browsers are available on most platforms, developing your game with Javascript allows it to be playable on multiple platforms without having to rewrite code.
  • Scalability: Javascript allows developers to easily scale their game from a small prototype to a full-fledged browser experience. It’s also much easier to extend existing code than start from scratch.
  • Rich environment: A huge range of libraries and frameworks are available to help developers create great games more quickly.
  • Game physics libraries: Javascript has access to physics libraries such as Matter.js, allowing developers to simulate real-world physics in their games with relative ease.
  • Easy distribution: Unlike native apps or PC/console games, Javascript games can be distributed through links or embedded in websites.

How to Choose the Right Game Engine for Your Project

Choosing the right game engine for your project can be a challenge. There are many options available, ranging from simple engines such as Playground.js to feature-rich options such as Construct 2 or Phaser. It’s important to choose one that best meets your needs for graphics, physics and performance.

For 2D games with simple graphics, a lightweight engine like PJCS would be a good choice. For 3D games or those requiring advanced graphics, Unreal Engine or Unity are recommended. You should also consider what platform you plan to deploy your game on and which engines support that platform.

Tips for Writing Clean and Efficient Javascript Code

Writing clear and efficient code is key to making sure your game runs smoothly and performs well in the browser. Here are some tips to help you write clean code:

  • Keep it structured: Divide your code into logical sections, use descriptive names, and use indentations so that others (and you!) can easily read and understand your code.
  • Use standards: Follow coding standards and conventions such as JavaScript Style Guide from Google’s Closure team and Code Conventions for the JavaScript Programming Language from Crockford on JavaScript for writing code that’s easy to read, maintain and debug.
  • Consistent coding style: Use abbreviations and acronyms sparingly for variables and functions, use consistent declaration style for functions, such as using uppercase for constructor functions, use consistent spacing around operators and parentheses when writing expressions, etc.
  • Keep things organized: Utilize OOP (Object Oriented Programming) principles such as encapsulation, abstraction and inheritance when creating game objects. This will keep your code structured and organized, giving you less bugs and more stability.

Understanding the Basics of Game Design with Javascript

Good game design is key to creating great experiences. Whether you’re building an RPG or an arcade game, understanding the basics of game design will help you create compelling gameplay experiences. Important concepts such as balancing levels of challenge, creating meaningful goals/quests, designing level maps, developing AI behaviors and structuring rewards systems all need to be taken into account when designing games.

Popular Libraries for Developing Javascript Games

Developers looking for proven libraries can take advantage of popular libraries such as Pixi.js for 2D graphics rendering, GreenSock for animation or Playcanvas for 3D game development. These libraries can save you time and effort in many aspects of development such as graphics rendering or AI behavior.

Best Practices for Creating a Successful Multiplayer Game with Javascript

Due to its ease of deployment and cross-platform compatibility, Javascript is well suited for creating multiplayer games that players can access in their browsers. It’s important to consider network latency when creating multiplayer games, as latency times can make a huge difference in the enjoyment of players. Additionally, it’s important to focus on scalability in order to meet the growing needs of your game as it grows in popularity.

Tools and Resources to Help You Get Started with Javascript Gaming

Developers interested in creating their own browser-based games have access to a huge range of resources online. Here are some helpful tools:

  • JSGameBench: A collection of tools and frameworks for building 2D games with Javascript.
