JSnice如何进行重新命名Javascript变量的统计重命名？

Question

I got a code

  function TRXsOqoPf(pOGsWUBqK) { /** @type {string} */ var tirYFOEZF = ""; /** @type {number} */ var RSkZLANHy = ~-1; var dubtZzLcb = pOGsWUBqK["length"]; for (;RSkZLANHy < dubtZzLcb;++RSkZLANHy) { var kwrxHKpMQ = pOGsWUBqK["charCodeAt"](RSkZLANHy); tirYFOEZF += kwrxHKpMQ >= 55296 ? pOGsWUBqK[RSkZLANHy] : String["fromCharCode"]((kwrxHKpMQ + 55296 - 44613) % 55296); } return tirYFOEZF; } 

When I use jsnice.org with STATISTICAL RENAMING ? I get

 /** * @param {Object} params * @return {?} */ function TRXsOqoPf(params) { /** @type {string} */ var optsData = ""; /** @type {number} */ var i = ~-1; var l = params["length"]; for (;i < l;++i) { var bc = params["charCodeAt"](i); optsData += bc >= 55296 ? params[i] : String["fromCharCode"]((bc + 55296 - 44613) % 55296); } return optsData; } ; 

How can JSnice do that? Is there any way for me to rename that variables by using php code?

Long story short: JSNice is based on a probabilistic model trained on millions lines of JavaScript code.

If you are interested in more details, please take a look at Nice2Predict website that interactively describes the process.
