title: Give me some javascript exercises please
body: <p>The best way I learn anything is by practice and exercise questions. Right now looking at getting familiar with javascript.
  I did some basic exercises , but am unable to find more on the internet.</p>
  
  <p>Can you people give me some questions to practice and learn javascript.
   Nothing complicated, just one liners would do.</p>
  
  <p>Example: "increase the size of an image gradually on mouseover." This example I thought for myself, but am struggling to think of more examples . I am bad at thinking for myself I guess. </p>
  
  <p>I have marginal experience in C# and java .
  Reason for learning javascript : to be able to write some firefox extensions</p>
  
  <p>Thanks</p>
  
  <p>Edit: I am looking for simple exercises</p>
