One of the simplest JavaScript commands to use is the alert() method. After you use this command correctly, the JavaScript alert box will pop-up. Here is an example of the alert() method:

alert('test');

If you place this snippet of code into your JavaScript program, you can test your code. By seeing the alert box in your browser, you know your JavaScript code is executing.

When not used for testing purposes, the alert box can be used to get your visitors' attention. You will see the alert box used a lot for warnings and errors.

Where you place the alert box code, will determine when the alert box will appear to the user. If you place the JavaScript code in the <head> part of your webpage, then your users will see the alert box right away before the HTML renders.
