Why is quinoline aromatic?

Quinoline is aromatic because it satisfies all the conditions for a compound to be aromatic.

For a compound to be aromatic,it should be-(i)planar(ii)conjugated(iii)have 4n+2 delocalised pi electrons

Quinoline has 10 delocalised pi electrons(which satisfies condition no. (iii)).It is conjugated(which satisfies condition no. (ii)).It is planar(which satisfies condition no. (i))

so there is no reason for it to be not aromatic.So Quinoline is aromatic
