Create a Hello World Program

Now that you have installed Bun Js on your system, you can start writing and running JavaScript code with it. To create a simple Hello World program, you can use your code editor to create a file named hello.js in your current directory and write the following code in it:

console.log("Hello, world!");

This code uses the console.log function to print a message to the standard output stream. This function is part of the Web-standard Console API that Bun Js provides.

You can also use other Web-standard APIs with Bun Js, such as fetch, WebSocket, FormData, etc. These APIs are based on the specifications defined by the World Wide Web Consortium (W3C) and are widely used by web developers. Bun Js implements these APIs using native libraries and modules, so you don’t need to install any external dependencies or polyfills.

Run the Program

To run the program, you can use the bun run command in your terminal. For example, you can run the following command to run the hello.js file:

bun run hello.js

This command will execute the JavaScript code in the file and output the result to the standard output stream. You should see something like this:

Hello, world!

The bun run command has some options and flags that you can use to customize its behavior. For example,

--watch flag: Watch for changes in the file and rerun it automatically
--debug flag: Enable debugging mode and attach a debugger to the process
--inspect flag: Enable inspection mode and connect a browser or an IDE to inspect the code
--help flag: See all the available options and flags
