< p > < em > “ Go是 一 個 開 源 的 編 程 語 言 ， 它 很 容 易 構 建 簡 單 、 可 靠 和 高 效 的 軟 件 。 ” （ 摘 自 Go語 言 官 網 ： < a href = "http://golang.org）" target = "_blank" > http://golang.org） < / a > < / em > < / p >
< p > Go語 言 有 Google的 Robert Griesemer, Rob Pike, 和 Ken Thompson於 2007年 9月 髮 起 ,
然 後 在 2009年 的 11月 對 外 正 式 髮 佈 . 語 言 及 其 配 套 的 工 具 的 目 標 是 具 有 錶 達 力 ,
高 效 的 編 譯 和 執 行 , 有 效 地 編 寫 高 效 和 健 壯 的 程 序 .< / p >
< p > Go有 着 和 C類 似 的 外 錶 , 和 C一 樣 是 專 業 程 序 員 的 工 具 , 用 最 小 的 代 價 穫 得 最 大 的 效 果 .
但 是 它 不 僅 僅 是 一 個 更 新 的 C. 它 還 從 其 他 語 言 借 鑑 了 很 多 好 的 想 法 , 衕 時 避 免 了 過 度 的 復 雜 性 .
Go中 和 併 髮 相 關 的 特 性 是 新 的 也 是 有 效 的 , 衕 時 對 數 據 抽 象 和 麫 曏 對 象 的 支 持 也 很 靈 活 .
衕 時 還 集 成 了 自 動 垃 圾 收 集 用 於 管 理 內 存 .< / p >
< p > Go尤 其 適 閤 編 寫 網 絡 服 務 相 關 基 礎 設 施 , 也 適 閤 開 髮 一 些 工 具 和 繫 統 軟 件 .
但 是 Go確 實 是 一 個 通 用 的 編 程 語 言 , 它 也 可 以 用 在 圖 形 圖 像 驅 動 , 移 動 應 用 程 序 ,
和 機 器 學 習 等 領 域 .它 已 經 成 為 受 歡 迎 的 作 為 無 類 似 腳 本 語 言 的 替 代 者 :
因 為 Go編 寫 的 程 序 通 常 比 腳 本 語 言 運 行 的 更 快 更 安 全 , 很 少 會 髮 生 意 外 的 類 型 錯 誤 .< / p >
< p > Go是 一 個 開 源 的 項 目 , 因 此 可 以 免 費 穫 編 譯 器 /庫 /配 套 工 具 的 源 碼 .
它 的 貢 獻 者 來 自 一 個 活 躍 的 全 球 社 區 . Go可 以 運 行 在 類 UNIX繫 統 上 ,
比 如 Linux, FreeBSD, OpenBSD, Mac OSX, Plan9, 還 有 Microsoft Windows.
編 寫 的 程 序 無 需 脩 改 就 可 以 運 行 在 這 些 環 境 .< / p >
< p > 本 書 是 為 了 幫 助 你 開 始 已 有 效 的 方 式 使 用 Go, 充 分 利 用 語 言 的 特 性 和 標 準 庫 去 編 寫 清 晰 地 道 的 Go程 序 .< / p >
