## nullCake

1. check if the data is null or undefined

### example

```javascript
import nullCake from "nullCake";

const myDataCheck = nullCake();
//getType
const myDataType = myDataCheck.getType(data);
//check data
const isNull = myDataCheck.check(data);
// translate data to targetType
const myDataNew = myDataCheck.setData(datatypeObj, dataObj);
```

### methods

| Method  | Description                                    |
| ------- | ---------------------------------------------- |
| getType | get data type ,return data's type in lowerCase |
| check   | check if the data is null or undefined         |
| setData | translate data to targetType                   |

#### use methods

1. getType

   - get data type ,return data's type in lowerCase

```javascript
const data = "get my data type";
const type = nullCake.getType(data);
console.log({ type }); // type: 'string'
```

2. check

   - check if the data is null or undefined

```javascript
  const data = null
  const isNull = nullCake.check(data)
  console.log({isNull}) // isNull: true
  --------------------------------------------------------
  const dataString = 'null' | 'Null' |'NULL'
  const isNull = nullCake.check(dataString)
  console.log({isNull}) // isNull: 'null string'
  --------------------------------------------------------
  const dataUndefined = undefined
  const isNull = nullCake.check(dataUndefined)
  console.log({isNull}) // isNull: 'undefined'
  --------------------------------------------------------
  const undefinedStr = 'undefined' | 'Undefined' |'UNDEFINED'
  const isNull = nullCake.check(undefinedStr)
  console.log({isNull}) // isNull: 'undefined string'
  --------------------------------------------------------
  const data = 'string' | [] | ...
  const isNull = nullCake.check(data)
  console.log({isNull}) // isNull: false
```

3. setData
   - translate data to targetType

```javascript
const targetData = { a: "", b: [], c: 0, d: () => {} };
const orginData = { a: "had a value", b: null, d: undefined };
const tData = nullCake.setData(targetData, orginData);
console.log({ tData }); // tData: {a: 'had a value', b:[], c:0, d:()=>{}}
```
