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);
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
- 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.
- 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
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.
