Now,the point is about your choice and likinigs. You need to choose either web or mobile. Thats definitely your concern, we even don't know which will suit you or how well you can be habituated with those. It always varies from person to person, so make a choice by yourself. Just one thing keep in mind, learning a new thing never goes in vain. Good luck.
