Should be noted that if this is ran on the Blog homepage, it instead returns the first listed Post ID instead of the blog homepage ID.

- If you are looking for conditional checks (i.e. if its this page, do this), is_single() checks if its the single post version of an ID. There are also other for homepage, page, etc. Check the other conditionals for others: https://codex.wordpress.org/Conditional_Tags — By michaeldhayes — 2 years ago

Post Anchor Identifier
get_the_ID() can be used to provide a unique anchor in a script. For instance, a dynamically-generated drop down menu with actions for each post in an archive could have
```
<?php
	$id = get_the_ID();
	$dropdown = "<select name='dropdown-".$id."' >";
	$dropdown .= "<option id='option1-". $id ."'>Option 1</option>";
	$dropdown .= "</select>";
?>
```
This would allow us to use JavaScript to control the element as it has a unique ID, and when submitting it as a form through the POST or GET methods the dropdown box will be sent with a unique ID which allows the script to note which post it is working on. Alternatively a hidden variable could be sent which will allow the script to see which post the submission is referring to
```
<?php
	echo '<input type="hidden" name="activepost" id="activepost" value="'.get_the_ID().'" />';
?>
```

In some cases, such as when you’re outside The Loop, you may need to use
get_queried_object_id() instead of get_the_ID().
```
$postID = get_queried_object_id();
```
