### How to use it?

`objectKeysToCamelCaseV2` and `objectKeysToSnakeCaseV2`

### Two available functions

- convert object keys from `snake_case` to `camelCase`

```ts

import { objectKeysToCamelCaseV2 } from 'keys-converter';

const user = {
	_id: "sf2309sdf0010",
	company_name: "some name",
	user_password: "some@pass123",
	created_at: "2020-01-01",
	updated_at: "2020-01-01"
};

const result = objectKeysToCamelCaseV2(user);

console.log(result);
> `{
	_id: "sf2309sdf0010",
	companyName: "some name",
	userPassword: "some@pass123",
	createdAt: "2020-01-01",
	updatedAt: "2020-01-01"
  }`


```

- convert object keys from `camelCase` to `snake_case`

```ts

import { objectKeysToSnakeCaseV2} from 'keys-converter';

const user = {
	_id: "sf2309sdf0010",
	companyName: "some name",
	userPassword: "some@pass123",
	createdAt: "2020-01-01",
	updatedAt: "2020-01-01"
};

const result = objectKeysToSnakeCaseV2(user);

console.log(result);
> `{
	_id: "sf2309sdf0010",
	company_name: "some name",
	user_password: "some@pass123",
	created_at: "2020-01-01",
	updated_at: "2020-01-01"
}`


```

The function `objectKeysToCamelCaseV2` receives an object.
You can to infer the return type as argument so the result returned will have types

#### Inference `result` and `input`


```ts
const user = {
	_id: "sf2309sdf0010",
	companyName: "some name",
	userPassword: "some@pass123",
	createdAt: "2020-01-01",
	updatedAt: "2020-01-01"
};

/** Dynamic Type */
interface ResultType {
	_id: string;
	company_name: string,
	user_password: string,
	created_at: "2020-01-01",
	updated_at: "2020-01-01"
}

const result = objectKeysToSnakeCaseV2<ResultType>(user);

```

If you provide the input type the function will validate the arguments,
So if you provide the result type the returned value will have "types"

## Warning

> - Function does not remove the first underscore for security

example
If your object has a protected prop like `_id` It will keep it
