I am just a newbie in web-dev . i heard of many questions like ideas for creating portfolio, what is a good portfolio etc. i am eager to know that what actually is a portfolio for a web-developer?
I would have thought it to be the web-development you had done before. Put it into a portfolio so your potential employer can use it as a point of reference for hiring you. Just like a fashion designer a portfolio of his or her past artwork to saw potential clients.
Not sure that would answer your question.
Portfolio: A folder, or container that contains work personally done for people to see. Typically showcasing your talent.
I think a good portfolio should not only showcase your previous work, but should also give a good representation of your personality. Anyone viewing it should be able to tell what sets you apart from everyone else.
