Coloured letters

On this JavaScript homework page we look at a question that might be appropriate after the students have learnt about the document object model. Unfortunately those teaching historical JavaScript are likely to ask it much earlier in the course than they should.

Just theConsonants

When someone is looking for a homework question to give their ‘history of JavaScript’ class they may come across a question intended for those learning JavaScript programming. If they decide to use that question for their class then the answer they expect could be very different from what the question is supposed to be asking for.

Practice

Knowing how to approach problem solving is one thing. Finding ways to practice complex problem solving when all of the programming tasks you have are trivial is something else. One possibility is to take an unsolved mathematical conjecture and use it to practice your problem solving skills. You are unlikely to actually solve it but you should be able to work out ways to tackle at least parts of the problem. You can then compare where you got to in say half an hour’s analysis with where the mathematical experts have got to in all the years they have worked on it. How much of what is already known about the problem did you figure out?

Loops and Recursion

When a problem can be broken up into smaller problems that are the same or similar to each other, then a loop or recursion may be an appropriate approach to reduce the solution to the overall problem to just a single iteration.

I’ve Uploaded MyImagesbut they Still Don’t Appear

This is one of the most commonly asked questions for people just starting out with creating their first web site. There are a large number of reasons why images might not appear on a new web site but some of them are far more likely than others. The obvious place to start if this happens to you is to check that you haven’t made one of the more common mistakes that are the most likely explanations for this problem.
