Do you sometimes feel left out or that you may be limiting your future career prospects? I am a Java application developer with also limited exposure to web development and it is difficult to not feel disconcerted with all the JavaScript talk.<p>I&#x27;ve started tinkering around with NodeJS but I&#x27;d hate for it to get lambasted just as soon as I&#x27;ve mastered it. The frameworks and tools in web development feel transient to me, and I&#x27;d hate to build my career on a foundation made of sand.
