### JavaScript BigInt

JavaScript BigInt represented numbers using the Number primitive type, but there were limitations when dealing with very large integers. Enter BigInt, a new numeric primitive in JavaScript designed to handle integers of arbitrary precision. BigInts can represent integers with arbitrary precision, allowing developers to work with numbers beyond the constraints of traditional JavaScript numbers.

Creating a BigInt:
You can create a BigInt by appending an “n” to the end of an integer literal or by using the BigInt constructor.

`let bigIntLiteral = 123n;let bigIntConstructor = BigInt(456);`

In the below PDF we discuss about Javascript BigInt in detail in simple language, Hope this will help in better understanding.

#### Operations with BigInt:

BigInt supports standard mathematical operations, and you can mix BigInt with regular Number types in calculations.

`let bigInt1 = 123n;let bigInt2 = BigInt(456);let result = bigInt1 + bigInt2;console.log(result); // Outputs: 579n`

#### Comparison with BigInt:

You can compare BigInt values using standard comparison operators.

`let bigIntA = 123n;let bigIntB = BigInt(456);console.log(bigIntA > bigIntB); // Outputs: false`

Use Cases:

• Cryptographic Operations: BigInt is particularly useful in cryptographic operations where precision is crucial. Encrypting and decrypting data often involves handling large integers, and BigInt ensures the accuracy required for such tasks.
• Financial Applications: Financial calculations often deal with large numbers that can exceed the safe range of regular JavaScript Numbers. BigInt becomes invaluable for precise computations in applications related to banking, investment, and accounting.
• Mathematical Computations: BigInt can be employed in mathematical algorithms that require high precision, such as calculating factorials, working with large prime numbers, or solving complex mathematical problems.
• Handling Large Datasets: In scenarios where datasets involve large numeric values, BigInt provides a reliable way to perform calculations without sacrificing accuracy or encountering overflow issues

#### Related Question

JavaScript BigInt is a data type introduced in ECMAScript 2020 to represent arbitrary precision integers. It allows developers to work with integers beyond the limits imposed by the standard JavaScript Number type.

The standard JavaScript Number type has a maximum safe integer value, and operations beyond that limit may result in inaccurate calculations. BigInt was introduced to address this limitation, providing a way to work with integers of arbitrary precision.

To declare a BigInt, append the letter ‘n’ to the end of an integer or use the BigInt() constructor.

BigInt consumes more memory than regular numbers due to its ability to represent larger integers. The memory used by BigInt is proportional to the size of the integer it represents.
