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At some point, it may be superseded by do blocks, but for now it's really your best bet.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.

'The best thing we can do today to JavaScript is to retire it,' says JSON creator Douglas Crockford • DEVCLASS
Tomorrow, do expressions:

- Map.prototype.emplace
-
When using 'new Map()' object, what is the simplest way to implement checking if a value exists then incrementing it by 1? (If not found, initialize to 0)
There's a stage 2 proposal for map.emplace() that's exactly what you're looking for:
-
Set methods proposal reaches stage 3
I'm also looking forward to map.emplace() and arr.group() and iterator helpers.
-
Is there a concise way to set a key's initial value in a Map object?
Sounds like you want emplace?
-
[AskJS] What are still present issues in contemporary (2022) JavaScript?
There's a proposal to give [emplace to maps](https://github.com/tc39/proposal-upsert).
