JavaScript: Hello, World!
As is tradition, we'll start by writing a 'Hello, World!' program. The program will print the following text:
Hello, World!
To print something, you need to give computer a special command. In JavaScript, we use console.log().
Instructions
Copy the exact code from the instructions into the editor and run it by clicking “Run”.
console.log('Hello, World!');
Note that if you type hello, woRld! instead of Hello, World!, it will count as different text, because upper and lowercase letters are different symbols in JavaScript. Letter size is called case, and any programmer will tell you that case is important. This rule affects almost everything in coding, so make sure you get used to paying close attention to the case at all times.
