What is the purpose of のある in 人気のある?


The full sentence was 人気のある情報を見る, found on a button. Why would のある instead of
for instance な




人気 works both as a noun ("popularity") and as a no-/na-adjective ("popular").
The following sentences mean the same thing:

_"Pokémon is popular with children."_

  * ポケモンは子供に人気です。
  * ポケモンは子供に人気があります。

English speakers don't usually say "there is popularity", but Japanese
speakers do say 人気がある for whatever reason. Both sentences are very common and
I don't even know which is more common.

Naturally, you can construct relative clauses from them. The following noun
phrases mean the same thing:

_"a Pokémon which is popular with children"_

  * 子供に人気なポケモン
  * 子供に人気のポケモン
  * 子供に人気があるポケモン
  * 子供に人気のあるポケモン
