ESLint is Now Language-Agnostic: Linting JSON, Markdown, and Beyond
ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
@types/bn.js
Advanced tools
@types/bn.js provides TypeScript type definitions for the bn.js library, which is a big number library for arbitrary-precision arithmetic. It is commonly used in cryptographic applications and blockchain development.
Basic Arithmetic Operations
This feature allows you to perform basic arithmetic operations such as addition, subtraction, multiplication, and division on big numbers.
const BN = require('bn.js');
const a = new BN(123);
const b = new BN(456);
const sum = a.add(b);
console.log(sum.toString()); // '579'
Modular Arithmetic
This feature allows you to perform modular arithmetic operations, which are essential in cryptographic algorithms.
const BN = require('bn.js');
const a = new BN(10);
const b = new BN(3);
const mod = a.mod(b);
console.log(mod.toString()); // '1'
Bitwise Operations
This feature allows you to perform bitwise operations such as AND, OR, XOR, and NOT on big numbers.
const BN = require('bn.js');
const a = new BN('1010', 2); // binary
const b = new BN('1100', 2); // binary
const and = a.and(b);
console.log(and.toString(2)); // '1000'
Number Conversion
This feature allows you to convert numbers between different bases, such as binary, hexadecimal, and decimal.
const BN = require('bn.js');
const a = new BN('ff', 16); // hexadecimal
console.log(a.toString(10)); // '255'
big.js is a small, fast, and lightweight library for arbitrary-precision decimal arithmetic. It is less feature-rich compared to bn.js but is suitable for applications that require high precision with smaller numbers.
decimal.js is a library for arbitrary-precision decimal arithmetic. It offers a wide range of mathematical functions and is more feature-rich compared to big.js, making it a good alternative to bn.js for applications requiring decimal arithmetic.
bignumber.js is a library for arbitrary-precision decimal and non-decimal arithmetic. It is similar to bn.js but focuses more on decimal arithmetic, making it suitable for financial calculations.
