HVSTAT DEV NOTES

General programming remarks

Always use easy to understand variable names. Always put var in front of a newly declared variable, to avoid scope issues.

Optimization Hints

Try to put all variable declarations at the start of the function (not strictly required).

Write efficient loops:

• Original loop: for (var i = 0; i < 10; i++) {}
• Efficient loop: var i = 10; while (i--) {}
• Performance: Great;

Always use === instead of ==. If the types being compared are the same, both will return true at the same time.

• Fast: if (0 === "0") //returns false;
• Slow: if (0 == "0") //returns true; Converts the type of "0" for the test(SLOW);
• Performance: Great if types are different;

regex.test(string) is faster than string.match(regex).

• Fast: /^http:///.test(string);
• Slow: string.match(/^http:///);
• Performance: Okay.

Don't use regex if possible. It can be extremely slow.

jQuery and jQuery UI must not be used except on the dialog panel for performance reason.
