Something related to code maintenance that you may have neglected to think about is the use of blank lines. Opinions will vary wildly as to what's right and wrong in this area, but I like the suggestions provided by Nicholas Zakas in his book Maintainable JavaScript. He says, "Blank lines should be used to separate related lines of code from unrelated lines of code." To demonstrate, here is a chunk of code similar to the one used in his book:
if (one && two.length{
  for (i = 0, l = two.length; i < l; ++i{
    j = one[i];
    k = this.doSomething();
    if (this.something) {
      if (this.anotherThing) {
      } else {

The code itself is meaningless and only theoretical. But we can improve our ability to scan this chunk of code by using blank lines. Here's the same code, improved:
if (one && two.length) {

  for (i = 0, l = two.lengthi < l; ++i{
    j = one[i];
    k = this.doSomething();

    if (this.something) {

      if (this.anotherThing) {
      } else {

You can instantly see the difference just by scanning each block. I like Zakas' literary analogy when he says, "code should look like a series of paragraphs rather than one continuous blob of text." He recommends blank lines before flow control statements, between methods, before comment lines, and between logical sections inside methods.

I'm sure many of you do this sort of thing already, but I've certainly seen code that doesn't use blank lines too often, so this might be a good reminder for many of you who haven't started doing it, or those of you who are like me and don't necessarily have a standard system in place for using blank lines.
