I am a commerce student and now I want to learn coding for developing website, games and ethical hacking. Can anyone suggest where to start?

Yes it's great platform but i don't know about where to start what language to learn first for starting

I'm a commerce student too.

The best decision I took in my life was to pursue BCA instead of BBA after 12th (Since Engineering Programs didn't allow commerce students to apply)

If you're already past that phase of picking a grad program, I recommend you start by picking up a few extensive courses on Udemy and giving your all in. Courses that sound like Fundamentals of computer engineering, end to end full stack development, or Complete Cyber Security Fundamentals would benefit you in landing your first job.

Alternatively, you can also pick some institutions that help you with a rigorous bootcamp and can help you get placed past 6 months of training. Whatever people say about them, I've seen that they work.

Please understand one thing - You wouldn't understand everything that you'd be taught. Things will go off the top of your head when you first start. But a few years into the game, everything will make sense. Good luck
