Why would you ever write some code using some operator, if you don't know its meaning?
And what's wrong with just reading Java documentation?

And who told you this code is Java? It can be Javascript, which has nothing to do with Java. Please don't tell us "I know it's Javascript". Not quite. Just mentioning "Java" is enough to see it.

You don't even know the name of the language of the name you are writing in, forget about the language knowledge itself. Let me ask you: why writing anything at all then? Just to waste your and our time? You got a big fat vote of 1 here, sorry.

Im not familiar with javascript, just need them converted to use with my net project !

Get familiar first, at least know the name of the language. Read some manual, try to write code, then ask your questions.

If you don't help me , fine just don't spam !

The spam is yours, not mine. I am helping you to make a serious decision: stop being lazy and start using your brain; and this is the most important help you need. If you don't want it and want to be rude instead, who is the looser? and anyway, you should stop spamming the site, because helping people with such attitude is useless.

Good luck,

Solution 1

Its a Bitwise XOR operator. Please have a look at below link for more Bitwise operators.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Bitwise_Operators

Have a look at online Bitwise operator calculator.

Hi bro just a few more doubts about this booleon function in js

e == 64 ? j[h++] = String.fromCharCode(b) : f == 64 ? j[h++] = String.fromCharCode(b, c) : j[h++] = String.fromCharCode(b, c, d);

i hardly can't understand this, and also i want to convert into .NET.

RaisKazi 24-Nov-13 22:09pm

Its Ternary Operator. And whats the reason you Accepted answer and then unaccepted it?

From me, a 5 for the answer, by the way... :-)

Thank you, SA! Yes, OP should learn basic programming first.

Sergey Alexandrovich Kryukov 25-Nov-13 11:46am

You are welcome. No, I'm not talking about knowledge now, we all need some time to learn...
