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.

A generically typed pipe function in TypeScript
An easier alternative is to wrap the value into an array, then use .map for each function in the chain, and finally escape the value with [0]
I made a similar data structure to allow adding side effect (no return value) as part of the chained function.

TypeScript Is Surprisingly OK for Compilers
> no pattern matching/switch expressions
They're still waiting on the do expression proposal for that (https://github.com/tc39/proposal-do-expressions), which has been in the bikeshedding stage for the past five years.

[AskJS] Opinions on using self executing functions as multi-line expressions.
At some point, it may be superseded by do blocks, but for now it's really your best bet.

What is this called? { id ? <Dashboard/> : <Login/> } and can I make it check for multiple things like a switch case?
But there is a proposal for do-expression : https://github.com/tc39/proposal-do-expressions

Using {Blocks} in Rust & Go for Fun & Profit
It's also the reason why do expressions are my most anticipated feature for JS.

Pipe Operator (|>) For JavaScript
> They should repurpose `do` so that `do {}` (without the `while`) is an expression that you can put statements inside and return the last statement.
There's a proposal for precisely that. Unfortunately, only Stage 1 though.

- Is a single ternary operator inside the returned JSX acceptable?
-
[AskJS] Is there ever a good use for loose blocks in JS?
It's one of the main reasons why I really want the do-expression propsal to work out, because then it would become:

[AskJS] What are still present issues in contemporary (2022) JavaScript?
Do blocks. Okay, this is actually a proposal so maybe someday. Basically blocks that can resolve to an expression.
