I want to do internship as a full stack developer but I'm unable to find any company. If anyone can help me so please reply.
Location:- New Delhi

Maybe try frontend first and then backend. As fullstack isn't that common as a job/Internship yet. Because it needs a whole bandwith of knowledge parts and expirience, which goes beyond the scope of an internship.

@heyheni Thank you. Will you please tell me, which language is in demand in front-end and back-end

@vsthakur Language demand can vary depending on location, industry, if this is in-house or outsourced, consulting and so on.

I would normally just browse my local popular job market websites, filter by a few languages and see how many results will show up.

@arraysstartat1 Thank you

@vsthakur first thing you should learn is how to search stuff on the internet.
It's the essential skill to master if you want to be a developer.

1. frontend: vue.js is in high demand to build webapps.
2. backend: google "backend development internship in gurgaon" and you'll see what is expected

@heyheni these are google dorks.
I know this.

Just wondering what have you studied or are studying currently in New Delhi?
