This kata needs more info in the bomb 'is something missing?'.I wanted to see if there were any clues in the files and I accidentally accessed the source code, That was not my intention. The way I accessed it (in my solution) should be blocked, since it avoids the 'require' restriction. I learned about this restriction from the exceptions messages.
It's a shame, because when you see the other bombs, they seem interesting

I'm stuck on bomb 7, the track 'Is something missing?' doesn't help.
Can anyone give me a hint on where I should look for what I need?
I don't know how to continue

I am stuck on last 3 bombs? It say "hint: 'Sorry, no more hints!!'" I really don't have idea.

It is still possible to get entire test.js file

// disable view source, I hope :)
try {
  {{ hidden }} =
    function () {
      return "Bombs can't be defused by cheating!! ;)";
    };
} catch (e) {}
Object.freeze(Object);
.....

Everything was working fine for me, I defused every bomb except the last one, understood what was needed, got "true" in the last statement, but tests were not passing. Couldn't understand what is wrong and looked up the answer for the last one. I rewrote Array.prototype.toString and it was working fine for me, but they rewrote Array.prototype.valueOf and it is working the same way, but only their variant is working in this kata. How should I find that out by myself?

I went and thought maybe the secret to diffusing one of the bombs would be written in a file, so I printed out the file contents of all the files in the directory.
You should really look to patch this, I had to forfeit the kata after I saw all of the diffuse methods in index.js.
The only thing the user needs to do is:

var fs = require('fs');
fs.readFile('/home/codewarrior/index.js', function (err, data) {
      if (err) {
         return console.error(err);
      }
      console.log(data.toString());
});

Any hint for Bomb #3?

Been sitting on this for a month, still don't have any idea whats "missing" for bomb #7. Any hints?

Where is the description of this kata? What should I do? The sample tests and the requirements are defined by myself?
I'm confusing about this kata.

Some people have cheated their way to the solution.
Is this acceptable?

How do you check global variables?

I'm stuck on the bomb which has this hint : 'is something missing?'

Can someone help me figure out what is missing?

I've tried just writing Bomb.diffuse() without any arguments but it doesn't work.
