Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

eslint-plugin-big-number-rules: Enforce finance-safe calculations (helps 0.1 + 0.2 really equal 0.3)
If you use floating-points for currency (instead of whole-numbers like you probably should) libraries like bignumber.js help keep your code away from the binary floating-point pitfalls of IEEE-754 which manifests in the standard JavaScript number type:
-
Solving the "floating point precision" problem with... floats?
This issue (well, another one in a widely used JS library) is what brought me to dig deeper into these "arbitrary precision" libraries and understand why this happens. I thought they were using rational numbers, but that's not the case. And this is what led me to think about how to solve this problem.

Web 3.0 frontend stacks in 2023
ERC20 has decimals fields and must be handled with digit awareness. I wanted to use only one library, but I used both ether.js's BigNumber and bignumber.js (for display purpose).

Handling currency values: facts and best practices
Most programming languages ( JavaScript, PHP, Go, Python, Java, C# ) have built-in support or 3rd-party libraries for handling this data type, even though the internal implementations can differ:
- BigDecimal equivalent. What do you use?

[AskJS] Are there numeric textbox widgets with built-in support for big numbers like decimal.js?
I'm working on a project where users will enter numbers like 9,999,999,999.99999 (up to 15 digits, up to 5 of them decimal) and we are having a problem with Numbers losing precision beyond certain number of digits (a typical issue for IEEE Standard 754 Floating Point Numbers, the 0.1 + 0.2 problem). I've solved this problem in a few projects before with the help of decimal.js or bignumber,js . In those cases, we kept user-input as strings and used a few custom-made numeric textbox widgets to accommodate this. Unfortunately, those widgets were proprietary... Now I need one again, but can't find anything. Do they exist?
-
Speeding up the JavaScript ecosystem - one library at a time
Either avoid floating-point, perhaps using BigInt, or use a library like BigNumber.js. (Incidentally, I wrote an eslint plugin to enforce its use.)
-
Best way to deal with excessive decimal results in calculator
To solve the problem while JavaScript waits on its own BigDecimal API, you can use something like bignumber.js to perform your calculations.

How can i prove that 0.1 + 0.2 = 0.3 is there like a function or ANYTHING i can do to bypass this error which occurs in most programming languages
You need to use something like BigNumber.js

Possible to request connection to a specific wallet? A web3 question
It seems like a rare solution. There's this library which claims to help but on its demo site it has the same problem as what my code has.

Build an entire NFT Collection on Ethereum using Solidity, Next.js, Web3Modal, Ethers.js
Now lets install Web3Modal library(https://github.com/Web3Modal/web3modal). Web3Modal is an easy-to-use library to help developers add support for multiple providers in their apps with a simple customizable configuration. By default Web3Modal Library supports injected providers like (Metamask, Dapper, Gnosis Safe, Frame, Web3 Browsers, etc), You can also easily configure the library to support Portis, Fortmatic, Squarelink, Torus, Authereum, D'CENT Wallet and Arkane. Open up a terminal pointing atmy-app directory and execute this command

Build a Web3 authentication flow with React, Ether.js, and Ceramic
The Web3Modal library is a simple Web3/Ethereum provider solution, which enables the addition of support for multiple providers in the application. The Web3Modal library supports the injected providers that we’ll rely on in this project, MetaMask and Tor.us.
- Is there a library that unifies connecting to wallets similar to what Solana has?
