## 概述
Go語言原生的`map`類型并不支持并發讀寫。`concurrent-map`提供了一種高性能的解決方案:通過對內部`map`進行分片，降低鎖粒度，從而達到最少的鎖等待時間(鎖沖突)

在Go 1.9中，引入了`sync.Map`。新的`sync.Map`與此`concurrent-map`有幾個關鍵區別。標準庫中的`sync.Map`是專為`append-only`場景設計的。

## 安裝
`go get github.com/orcaman/concurrent-map
`

## 實例
```

m := cmap.New()

m.Set("foo", "bar")

if tmp, ok := m.Get("foo"); ok {
	bar := tmp.(string)
}

m.Remove("foo")
```
