WordPress comes with many easy-to-use functions which are called into the themes where ever needed. How do you know the purpose of a function?
You can Google it and find the details or, you can also use the WordPress Theme Editor.
Documentation Lookup in Theme Editor
Navigate to Appearance > Editor on your WordPress Dashboard. Theme editor loads the style sheet of the currently active theme.
From the Right sidebar that lists all the files of the theme, choose the file that contains the function you want to learn more about.
