前提： Syntax很簡單，不用look ahead，而且都會知道要讀多少byte（沒有那種「讀到0x00為止」）

我的作法看起來長這樣：

const msgParser = expect([10, 10, 20], (datetime, messageType, messageID) => {
    switch (messageType) {
        case "HI":
            expect([10, 10], (senderID, senderName) => {
 // connect

現任職於博智雲端科技用python寫web app，下班後的身份是台灣城市單車聯盟理事、Cocoaheads Taipei發起人、業餘macOS/iOS開發者。上一個生涯目標是推廣熱愛的蘋果，已達成。接下來的生涯目標是推廣熱愛的單車多元文化，用單車來改變城市。曾主辦「沈默的騎行」呼籲重視交通安全，以及「台北裸騎」。
