How to make a JavaScript script

Learn how to create a JavaScript script, complete with an example, to make your webpages interactive.

Creating a JavaScript Script

Writing a JavaScript script is relatively easy. JavaScript is an interpreted language, so all you need to do is write the code and it will execute in the browser. In this tutorial, we will walk through the steps of writing a simple JavaScript script and go over some of the basic concepts.

Step 1: Create a File

The first step is to create a file to contain your JavaScript code. JavaScript files must have the .js extension. For this example, we will create a file called script.js.

Step 2: Write the Code

Now we are ready to start writing the code. For this example, we will write a simple script that prints a message to the console. Open the script.js file in a text editor and add the following code:

console.log("Hello World!");

This code will print the message “Hello World!” to the console when it is executed. The console.log function is used to print messages to the console.

Step 3: Execute the Code

Now that we have written our code, we need to execute it. To execute the code, open the script.js file in a web browser. When the browser loads the file, it will execute the code and print the message “Hello World!” to the console.

That’s it! You have written and executed your first JavaScript script. In this tutorial, we have gone over the basics of writing a JavaScript script. Of course, there is much more to learn about JavaScript and writing scripts, but this should get you started.
