JSLint preferred access method in javascript-- dot notation or array brackets?

Question

A coworker is running JSLint on our code and fixing the issues that come up. One change he made was to go from this:

document.getElementById(control["value1"]);

to this:

document.getElementById(control.value1);

Is it JSLint's preference to use the dot notation over array brackets? My understanding from here is that the brackets are a bit more flexible, and I wondered what the best practices from the field were.

Answer 1

Best practice is to use . notation unless you actually need to pass a variable.

This looks more normal, and also allows the JITter to do more intelligent things.
