# Generate json files

Run: `node --max_old_space_size=8183 generateJson.js`

Output: `Id to find:  p_xxx` (replace xxx with the actual number)

# Test 

Test maps: `go run ./map/speedTest.go p_xxx`

Test structs: `go run ./struct/speedTest.go p_xxx`

# Struct:

```

type PropertiesA []struct {

	History []struct {

		Timestamp int64  `json:"timestamp"`

		Value     string `json:"value"`

	} `json:"history"`

	Property string `json:"property"`

}

```

# Map:

```

type propertiesB map[string]map[string]string

```
