- "Podcasts are as good as vlogs."
This means podcasts are just as good as vlogs. - "Podcasts will be as popular as blogs."
This means podcasts will be just as popular as blogs.
So, "as ... as" shows that two things are equal.
not as … as
Use "not as ... as" when you want to say one thing is not as good or not as much as the other.
not as + adjective + as
Example:
- Running a marathon is not as easy as running a 5k.
