Linux OS for a new user

Hello users,

This question may be offtopic here, but i need your kind suggestions. I am now going to reinstall an operating system in my computer.
I had Windows 10 earlier. Now I am thinking to use Linux. I have not used it before so I have a few doubts.

Will it be difficult to use and understand Linux?
Will Linux be faster than Winodows 10?

Thanks

Linux will be easier for development if you prefer to run and install application using terminal / console.

Install linux and then use the console to install vue-cli to speed up your initial need to start develop vue!

Answers to both questions depend on which desktop environment you will choose to use. Some are faster but have less features, some look like Windows, some like Mac or mobile, etc. Just google “linux desktop environments”, look for screenshots and description and pick the one which suits you most.
