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

Just a guess here, but it may be time for functional decomposition. Functions should do one thing and do it well.

Too many vars is suggestive of a function that's trying to do too much. Or a case where you should be using an array.
