The result depends heavily on the data input.
# Usage
100% compatibility with standard lib
Replace
```go
import "encoding/json"
json.Marshal(& data)
```
2020-12-17 12:28:29 +00:00
with
2020-02-17 12:15:57 +00:00
```go
2020-12-17 12:28:29 +00:00
import jsoniter "github.com/json-iterator/go"
2020-02-17 12:15:57 +00:00
var json = jsoniter.ConfigCompatibleWithStandardLibrary
json.Marshal(& data)
```
Replace
```go
import "encoding/json"
json.Unmarshal(input, & data)
```
with
```go
2020-12-17 12:28:29 +00:00
import jsoniter "github.com/json-iterator/go"
2020-02-17 12:15:57 +00:00
var json = jsoniter.ConfigCompatibleWithStandardLibrary
json.Unmarshal(input, & data)
```
