In addition, for users, everyone prefers a fast website over a slow one

POST or PAGE or custom content all come from the same database table of wordpress. Where POST ID is the primary key to bind other strings. Let's see a wordpress REST API example related to post 

https://www.jaybranding.com/wp-json/wp/v2/posts/

Thus, all WordPress data is saved in the form of POST template. Then defined into different formats such as ROOM, SERVICES, PAGE, TAG, CATEGORY ...

And other extra features such as: save languages, save revisions, save drafts, save media...

Therefore, in the programmer's experience, in addition to looking at the URL, you also have to know how to see the post's ID. For example, when editing, notice the text postID = ###

Default to access a page without remembering the link by www.website.com/?p=123 (123 is the post ID)

In addition, to add a custom field, you can use the default custom field of wordpress (not user-friendly). Or use the PODS plugin. See instructions here

File wp-config.php – This is the connection file between the MySQL database and the PHP code. In this file will contain username / password and database connection information. This is the first setting to do when making a wordpress website

WordPress Settings

• General: this is the second most important settings item in wordpress, it should be done right from the login step to the site. In it, do not leave any boxes blank
• Permalinks: the third importance because it will help the website to be clear and easy to read. As well as good for SEO and caching (default does not cache when the URL has parameters)
  
• Reading: starting to set up the web, this part can be done later, not too important
