Come si interpreta questo Script? [sono nuovo del javascript??mi date 1 mano?]

ciao raga sto analizzando e commentando 1 script...

var processing = false, controls = 0, surfTable, linksx, currentElement, links, surf, container, button,
iframe, watcher, clear, progress, red = 0, green = 255, blue = 0, started = false;

```cosa vuol dire???si limita semplicemente a creare la variabile processing assegnandole il valora false a creare la var surftable vuota etc???

c'e una altra cosa che non capisco con le mie conoscenze.. mi potete spiegare a parole semplici questo??

var devEnc = {
_keyStr : "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=",
sTokenRewind : function (input) {
var output = "";
var chr1, chr2, chr3, enc1, enc2, enc3, enc4;
var i = 0;
input = devEnc._utf8_sTokenRewind(input);
while (i < input.length) {
chr1 = input.charCodeAt(i++); chr2 = input.charCodeAt(i++); chr3 = input.charCodeAt(i++);
enc1 = chr1 >> 2; enc2 = ((chr1 & 3) << 4) | (chr2 >> 4);
enc3 = ((chr2 & 15) << 2) | (chr3 >> 6); enc4 = chr3 & 63;
if (isNaN(chr2)) {enc3 = enc4 = 64;} else if (isNaN(chr3)) {enc4 = 64;}
output = output + this._keyStr.charAt(enc1) + this._keyStr.charAt(enc2) + this._keyStr.charAt(enc3) + this._keyStr.charAt(enc4);

return output;

}
}
return utftext;

}
else if((c > 191) && (c < 224)) {

dai ragà ci sarà qualcuno che mi saprà aiutare almeno nel 1°punto...
