2. General Coding Principles
99% of code should be housed in external js files.
Include the file at the end of the BODY tag for maximum
performance.
All Boolean variables should start with "is".
isValid = (test.value >= 4 && test.success);
Minimize global variables - the less globals you create, the
better.
When specifying any global variable, clearly identify it
window.globalVar = { ... }
3. General Coding Principles
Name variables and functions logically:
For example: popUpWindowForAd rather than
myWindow.
Keep variables name meaningful.
Keep constants or configuration variables - at the top of the
document.
Comment your code!
4. White-space
keep one space after each comma and colon (and semi-
colon where applicable),
no spaces immediately inside the right and left sides of
parenthesis.
Which code is correct?
1.for ( var i = 0, j = arr.length; i < j; i++ ) 1.for(var i=0,j=arr.length;i<j;i++){
2.// Do something.
2.{
3.}
3.// Do something.
4.}
1.for (var i = 0, j = arr.length; i < j; i++) { 1.for(var i=0, j=arr.length;i<j;i++){
2.// Do something.
2.// Do something.
3.}
3.}
