JSLint It is not necessary to initialize undefined

While validating my JavaScript code in JSLint (www.jslint.com). I got a error I've never seen before. Is this something new ?

It tells me that:

It is not necessary to initialize 'i' to 'undefined开发者_运维问答'. On this:

var i = 0,
    l = data.d.ResponseData.length,
    x;

Does anyone know what this means?
