Nodejs 代码规范

空格

缩进 tab => 2空格

exports.print = function() {
  for (var i = 0, len = arguments.length; i < len; ++i) {
    process.stdout.write(String(arguments[i]));
  }
};

for, if 括号前后间隔 1空格

function format(value, recurseTimes) {
  // Provide a hook for user-specified inspect functions.
  // Check that value is an object with an inspect function on it
  if (value && typeof value.inspect === 'function' &&
      // Filter out the util module, it's inspect function is special
      value !== exports &&
      // Also filter out any prototype objects using the circular check.
      !(value.constructor && value.constructor.prototype === value)) {
    return value.inspect(recurseTimes);
  }
}

function 只需后 ) 与 { 直接间隔 1空格

function timestamp() {
  var d = new Date();
  var time = [pad(d.getHours()),
              pad(d.getMinutes()),
              pad(d.getSeconds())].join(':');
  return [d.getDate(), months[d.getMonth()], time].join(' ');
}

相等判断，使用 === , !==

readStream.addListener('data', function(chunk) {
  if (writeStream.write(chunk) === false) readStream.pause();
});
