JavaScript is as different from Java as chalk is from cheese. Tip: When testing this method, be sure to have the console view visible (press F12 to view the console). It mainly used in a web application with HTML and CSS. Let’s start by looking at the five lines we just added.This section of code begins and ends with what’s known as an This piece of code calls what’s known as a JavaScript function. To print a hello world in JavaScript follow the below steps. We'll take a closer look at Git in a later tutorial. The REPL environment that we’ll be using first First, open a browser such as Chrome and open the developer tools. This tutorial you will learn How to write a Hello World in an HTML page using a JavaScript Function. "); } hello(); The second way is the /* */ comment, which can be used for both single-line and multi-line comments. JavaScript is a very powerful and popular language nowadays. Now left click in your mouse and select option. Within the At this point you should see your updated URL by running the following command:Now that the GitHub remote URL is set, add the latest updates along with a commit message.Now that these changes have been pushed to GitHub your code is accessible to you at any time (thanks to the “cloud”) even if you delete the files on your computer. Functions are extremely useful in programming since you can create them once, use them n number of times. It should be pretty clear to anyone with even a basic grasp of HTML.We can now go ahead and write the JavaScript program.Add the following code after the

tag and save the file:That’s it! You’ve now successfully created a function in JavaScript. This In this tutorial, we will introduce you to some JavaScript programming fundamentals and create our very first “Hello World” program.Wikipedia defines JavaScript or JS as an “interpreted programming language” that allows “client-side scripts to interact with the user”.It’s okay if all that sounded complete mumbo jumbo to you.Let’s breakdown this definition into something a normal person could understand:JavaScript is primarily used to create interactive elements on a web page. git remote set-url origin https://github.com/your-username-here/webdev-intro.git The console.log() is a function in JavaScript which is used to print any kind of variables defined before in it or to just print any message that needs to be displayed to the user. Rather than have pop-up alerts that we need to continue to click out of, we can work with JavaScript by logging it to the Console with console.log. Learning JavaScript is essential to becoming a front end web developer. Afer this open parenthesis are zero or more “arguments” followed by a closing parenthesis and a semicolon to end the line.We’ve now written our first program in an HTML page. Java is heavily used in business software, while JavaScript is limited to use in web pages.With that little confusion out of our way, let’s dive right into JavaScript programming.“Hello World” is a staple of programming courses. Don’t worry about all of the punctuation (the parentheses, quotes, and semicolon) just yet. You can turn any piece of code into a function by wrapping it in { } brackets and adding “function functionName()” before it.Now that we’ve created the function, we can call on it any number of times.Add the following code anywhere between the tags:Now open the test2.html file in your web browser. This means they are written along with the HTML, though you can include them externally as well.To get started, we will first create a simple HTML file where we can include our JavaScript.Open your text editor and type the following code into it:Save this file as test.html (make sure to save as ‘All Files’ if using Notepad).This is a standard HTML template, nothing special about it.

The JavaScript alert() function is a command that pops open an Alert box and displays the message that appears inside the parentheses—in this case, hello world. In this case, the name of the function is When we call a function there’s a certain structure to how it’s called.
