这个订单有保证吗?(Is this ordering guaranteed?)

是这个脚本:

local data = 
{
  { "data1",    "1"},
  { "data5",    "2"},
  { "3453453",  "3"},
  { "zzz",      "4"},
  { "222",      "5"},
  { "lol",      "6"},
  { "asdf",     "7"},
  { "hello",    "8"},
}

local function test()
 local count = #data
  for i = 1, count do
    print(data[i][1] .. " = " .. data[i][2])
  end
end

test()

保证输出:

data1 = 1
data5 = 2
3453453 = 3
zzz = 4
222 = 5
lol = 6
asdf = 7
hello = 8

如果不是那么为什么,以及表现最佳的表现方式是什么?

  { "data1",    "1"},
  { "data5",    "2"},
  { "3453453",  "3"},
  { "zzz",      "4"},
  { "222",      "5"},
  { "lol",      "6"},
  { "asdf",     "7"},
  { "hello",    "8"},
}

local function test()
 local count = #data
  for i = 1, count do
    print(data[i][1] .. " = " .. data[i][2])
  end
end

test()

Guaranteed to output:

data1 = 1
data5 = 2
3453453 = 3
zzz = 4
222 = 5
lol = 6
asdf = 7
hello = 8

If not then why, and what is best way performance wise to make it so?

最满意答案

你必须填写所有的回调。

var HTTPParser = require('http-parser-js').HTTPParser;
var parser = new HTTPParser(HTTPParser.RESPONSE);
parser.onHeadersComplete = function(res) {
    console.log(res.headers);
};
parser.onBody = function(chunk, offset, length) {
    console.log("body", chunk.toString(), offset, length)
}
parser.onMessageComplete = function() {

}
parser.execute(new Buffer('HTTP/1.1 200 OK\r\nContent-Type: text/plain; xya\r\nContent-Length: 11\r\n\r\nhello world'))

You have to fill all the callbacks.

var HTTPParser = require('http-parser-js').HTTPParser;
var parser = new HTTPParser(HTTPParser.RESPONSE);
parser.onHeadersComplete = function(res) {
    console.log(res.headers);
};
parser.onBody = function(chunk, offset, length) {
    console.log("body", chunk.toString(), offset, length)
}
parser.onMessageComplete = function() {

}
parser.execute(new Buffer('HTTP/1.1 200 OK\r\nContent-Type: text/plain; xya\r\nContent-Length: 11\r\n\r\nhello world'))
