What is the reason behind JSLint saying there are “too many var statements”

Question

JSLint (with the onevar flag turned on) is flagging some javascript code that I have with the following:

Problem at line 5 character 15: Too many var statements.         


        

Answer 1

The idea is that you should use an object instead of individual vars. So where you have got:

var x = arg + 1,
    y = cache.GetItem('xyz');

Change it to:

var dimensions = {};
dimensions.x = arg + 1;
dimensons.y = cache.GetItem('xyz');
dimensions.request = ...

You can then access these variables through the object, its neater to have one object per function to contain that functions variables. Then you won't get the warning.
