Get an Editor
You’ll need a text editor and a web browser to get started. You can use any text editor you’re comfortable with, but I recommend using Visual Studio Code. It’s a free and powerful text editor for JavaScript development.
You can download it from the Visual Studio Code website. Another (not free) but outstanding editor is WebStorm.
Once you’ve installed Visual Studio Code, you must install the JavaScript extension. To do this, open Visual Studio Code and click on the Extensions icon on the left-hand side of the screen. Search for “JavaScript” in the search bar and click the “Install” button next to the first result.
Here is an impressive list of JavaScript extensions for Visual Studio Code. Next, you’ll need to create a new JavaScript file. To do this, click on “File” in the top-left corner of the screen and select “New File”. Save the file with a .js extension.
Start Coding
Now, you’re ready to code! Here’s a simple example to get you started:
function helloWorld() {
console.log(“Hello, world!”);
}
helloWorld();
This code defines a function called helloWorld that prints the message “Hello, world!” to the console. The last line calls the helloWorld function, which causes the message to be printed.
Test Your Code
To test your code, open your web browser and create a new HTML file. Add a script tag to the HTML file and set the src attribute to the location of your JavaScript file. For example:
<!DOCTYPE html>
<html>
<head>
<title>My JavaScript page</title>
</head>
<body>
<script src="hello.js"></script>
</body>
</html>
Save the HTML file and open it in your web browser. You should see the message “Hello, world!” printed to the console in the developer tools. Congratulations! You’ve now set up your development environment in JavaScript and written your first piece of code. Keep practicing and exploring the world of JavaScript programming!
