Beside vs. Besides

Asalamualaikum and Hello everyone,
I was facing a problem before this on distinguishing "beside" and "besides". I bet, some of you also might be facing this kind of problem these days, right?
Hence, i would like to share what i found on the internet ! 

First of all,
**Beside
The word beside is a preposition. It means close to or next to.

Beside = next to.

Example, if u wish to say about something that stands next to you, you should probably have said, 
      " Adam was standing beside me during the choir competition.."

Examples:

• Come and sit beside me. 
• Your hat is beside the dog basket. 

Meanwhile, 
**Besides
The preposition besides means in addition to or apart from.  As an adverb, it means furthermore or and another thing.

Besides = apart from / and another thing

Example, if u wish to say another point of a similar thing, you should probably have said,
      " Besides smoking, drinking caffein also not good to our health.."

Examples:

• Besides Craig, who else caught a bass? 
(Besides is a preposition in this example. Apart from Craig, who else...)
• Besides, it's not just about determination. 
(Besides is an adverb in this example. Furthermore, it's not just...)
