Nearly all internet websites employ the popular programming language known as JavaScript. A web application can be enhanced using JavaScript by adding animations and interactivity that improve gaming and web browsing.
JavaScript's capacity to create games that can be played readily online is a common topic that draws young people to learn how to program. It makes sense that more game developers have been adopting JavaScript to create new content over the past 10 years as both internet connections and computer hardware have improved.
Popular games in JavaScript
- 2048 You can move tiles around in a grid using the arrow keys in the addictive game 2048. The goal is to combine tiles till 2048 is reached. Interesting fact: I developed my first Python script to play this game for me automatically!
- Polycraft is a 3D game accessible through your browser. Adventure, exploration, base-building, gathering, crafting, and even fighting abound in Polycraft. It's a great illustration of how Javascript may help you progress beyond 2D games.
- React Native, a platform for building mobile applications is used to create the game Words With Friends 2 for mobile devices. React Native was the technology of choice for Zynga since it allowed for the development of a single code base, cross-platform game utilizing JavaScript.
How to Code a Game in JavaScript

Step 1 – Select a Code Editor
Go over to your preferred editor to get started. The examples shown here will make use of the CodeWizardsHQ editor, which is available to all of our coding students. You can use another online editor, such as CodePen, if you are not already enrolled in our programme.You can read more about technology here tekno bilim adamı
Step 2 – Build a Game Canvas
The first line of code we write will create the game's canvas. The height and width can be changed as necessary. There are 4 steps to this.
- Put your canvas code between the style> and /style> tags.
- Between your script>/script> tags, create your startGame function and establish your variables, and getCanvas.
- In the <body> and </body> tags, call startGame on load.
- If you'd like, include a title by adding an h1 tag inside the body tag.
The name of our game, Block Hopper, ought to appear in a rectangle in a pale blue color. This will serve as the setting for our game.
Step 3 – Code Your Player, The Hopper
Let's add our player next. This process will involve four steps.
- Create a player-named variable.
- Create a variable to store the player's Y position.
- Make a function named createPlayer() that takes three parameters: x-position, width, and height.
Using the function from step 3, construct our player and add it to the variable generated in step 1 in startGame().
Step 4 – Add Gravity to Your Player
Let's give the player some gravitational pull. These are the procedures.
- Make a fallSpeed variable.
- A new interval should be created and stored in a variable that executes our updateCanvas() method.
- Make two functions for our player: a drawing function and a moving function.
- Create a function called updateCanvas() that redraws the player and clears the canvas.
