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.

0.1 + 0.2 is not 0.3 in JavaScript.
That's because every number in JavaScript is represented using 64 bits floating point. Since numbers are saved in binary, there are some decimal numbers that are periodics in binary but not in decimal, e.g. 0.2, equivalent to 0.00110011001100110011... in bin. You can avoid this using some BigDecimals libraries like decimal.js, or, if you need to work in different bases, you have Basenumber.js

Node_modules: One character saved 50 GB of disk space
> Like, let's introduce a dependency for decrement lol
Here's a package that basically does that: https://www.npmjs.com/package/number-precision
Not entirely unreasonable as all `number`s are floats by default in JS, but the implementation of the entire package (https://github.com/nefe/number-precision/blob/master/src/ind...) is less than 100 lines of code and actually contains a method called "minus".
The very worst JS packages I've seen have got to be is-odd and is-even. 430,796 and 202,268 downloads every week, I kid you not!

Arrayality - Tiny puzzle which gives you freedom
qonvert - Qonvert lets you convert rational numbers between different bases and between different representations such as positional notation and improper, mixed, continued and Egyptian fractions, as well as Greek and Roman numerals. The numbers can have basically arbitrary size and precision.
