dayjs.duration is not a function

[galenguyer]

Describe the bug
After loading dayjs from unpkg.com, I ran the example code from the duration with diff section of the docs. The dayjs() function works fine, however when it gets to creating the duration with dayjs.duration(), I get the error Uncaught TypeError: dayjs.duration is not a function

Expected behavior
I expect a duration object to be created for me to use

Information

• Day.js Version v1.10.5
• OS: Arch Linux
• Browser Firefox 89

Hi @galenguyer,
You need to use the Duration plugin for that example to work:
