How to: Q. Explain BigInt data type in Node.js?
A BigInt value, also sometimes just called a BigInt, is a bigint primitive, created by appending **n** to the end of an integer literal, or by calling the BigInt() function ( without the new operator ) and giving it an integer value or string value.

**Example:**

```js
/**
 * BigInt Data Type
 */
const maxSafeInteger = 99n; // This is a BigInt
const num2 = BigInt('99'); // This is equivalent
const num3 = BigInt(99); // Also works

typeof 1n === 'bigint'           // true
typeof BigInt('1') === 'bigint'  // true
```
