Function DeepGet

DeepGet(
    obj: { [key: string]: any },

): any
Retrieves a value from a nested object using a dot notation key.

This function will never throws any error if there is a problem with the input type. It will return undefined instead. This also means that if the key is not found, the function will return undefined instead of null especially when working on JSON data.

- key: string
  The key in dot notation representing the path to the value.
- Optionaloptions: { sep: string }

  - sep: string
    Custom key separator (default: '.').
Returns any
The value at the specified key if it exists, or undefined if the key is not found or an error occurs.
Example: Simple object
```
const obj = { a: { b: { c: 42, d: { _: 'foo' } } } };
getValue(obj, 'a.b.d._');  // foo
```
Example: Array index notation
```
const obj = { a: { b: { c: [1, 2, 3] } } };
getValue(obj, 'a.b.c[1]');  // 2
