The result depends heavily on the data input. # Usage 100% compatibility with standard lib Replace ```go import "encoding/json" json.Marshal(&data) ``` with ```go import jsoniter "github.com/json-iterator/go" var json = jsoniter.ConfigCompatibleWithStandardLibrary json.Marshal(&data) ``` Replace ```go import "encoding/json" json.Unmarshal(input, &data) ``` with ```go import jsoniter "github.com/json-iterator/go" var json = jsoniter.ConfigCompatibleWithStandardLibrary json.Unmarshal(input, &data) ``` [More documentation](http://jsoniter.com/migrate-from-go-std.html) # How to get ``` go get github.com/json-iterator/go ``` # Contribution Welcomed !
