The best way to test the truthiness of a boolean

testBoolean.js

function testBoolean(boolean) {
  var booleanCharArray = (function (str){
    var buf = new ArrayBuffer(str.length*2); // 2 bytes for each char
    var bufView = new Uint16Array(buf);
    for (var i=0, strLen=str.length; i<strLen; i++) {
      bufView[i] = str.charCodeAt(i);
    }
    return buf;
  }(String(!!!!!!!boolean)));

  return (
    booleanCharArray[0] === 116 &&
    booleanCharArray[1] === 114 &&
    booleanCharArray[2] === 117 &&
    booleanCharArray[3] === 101
  )
}
