Tоday I was participating in a discussion on one Java forum – the question was if Java is an easy or difficult programming language to learn. IMO, Java is not difficult to learn, to teach, and to use. It’s a strongly typed compiled language with tools that help you identify most of the errors before you even run the program.
Ran the program – it rendered the Web page, HTML looks fins, but nothing worked. IDE didn’t give any errors. Started a browser debugger – Firebug. Now I’ll going to put a breakpoint in this newly added function and find the problem. How hard could it be? I’ve added just this little fragment to a working program. Easy Peasy.
Oops. Where is my main.js? Nowhere to be found. Only jQuery script is available.
Was my main.js even downloaded? Let’s check the Network tab. Yes, it’s here:
After applying deductive reasoning (as in Sherlock Holmes stories) I figured out that the script has arrived to the browser, which instead of adding it to the DOM, showed a middle finger without explaining why. As any normal person, I started to to find who someone else to blame. May be this Firebug is buggy and just doesn’t want to show my nice script? Tried Chrome with Developer Tools – same story. The script arrived, got the finger and I have nothing to debug.
What’s the moral of this story:
