JavaScript can display data in different ways using:
- `console.log()` Object
- `alert()` Object
- `document.write()` Object
- `elem.innerHTML` Property - `elem` is an arbitrary name.

### console.log()
As shown in the previous article, you can debug unexpected results from the browser in the console.

### *alert* method
The `alert` is a method on the browser `window` object - `window.alert(...)`. It is used to display data on the browser or screen (window). It displays the result in a modal dialog box.

### *write* method
To test for unexpected results directly in the browser window, the command `document.write()` is used. It allows **HTML** elements within the method. For example `document.write("Hello World
")`.
**index.html**
```html

### *innerHTML* property
The `innerHTML` property is used on selected elements to target specific elements based on their selector to allow HTML content within the element.
**index.html**
```html

Outside of the console, but in the *window browser*, you use the `alert` method on the `window` object or document property — `window.alert('...')`, `window.document.write('...')`, `window.document.querySelector('#demo') = "..."`.
