You can employ a number of shorthand JavaScript statements to tighten up your code. You can use numerous abbreviated assignments to shave a few bytes.
For example, this:
x=x+1;
y=y*10;
can become this:
x++;
y*=10;
You may also find that you can reduce simple if statements using a ternary operator, so this:
var big;
if (x > 10) {
big = true;
}
else {
big = false;
}
can become this:
var big = (x > 10) ? true : false;
If you rely on some of the weak typing characteristics of JavaScript, this can also achieve more concise code. For example, you could reduce the preceding code fragment to this:
var big = (x > 10);
Also, instead of this:
if (likeJavaScript == true)
{ /* something */ }
you could write this:
if (likeJavaScript)
{ /* something */ }
