I found a mimnaler version of the js:

function aa(i) { var str = "abcde"; var a = 0; var f; var e; var Y = 0; for (; e = str.charAt(Y++); f = a%4?0:e) { } }
deobfuscate it get error:

INFO duplicate of issue#5

I have the second issue too: TypeError: Expected node path of type Expression

I broke it down to:

var a;
a % 4;
