I've been experimenting with having `ts-blank-space` use the (unstable) TypeScript-go JS API. At first it was ~60% slower than using the TS 6 API, but with a bit of investigation, a bug fix, and a small refactor to use different API calls it is now ~24% faster! Draft PR: github.com/bloomberg/ts...

Terminal output of running ts-blank-space's `./bench.sh` script.

TS go has a mean of 972 milliseconds (+/- 7ms).

TS 6 has a mean of 1205 milliseconds (+/- 8ms).

So TS go ran 1.24 times faster.

```js
// London DST starts: 2026-03-29 01:00 -> 02:00
const zdt = Temporal.ZonedDateTime.from(
"2026-03-29T00:30:00+00:00[Europe/London]",
);

console.log(zdt.toString());
// → "2026-03-29T00:30:00+00:00[Europe/London]"

const plus1h = zdt.add({ hours: 1 });

console.log(plus1h.toString());
// "2026-03-29T02:30:00+01:00[Europe/London]" (01:30 doesn't exist)

Source maps are a vital part of modern web development, but the lack of a standard made it impossible for us to add new features or improve the debugging experience. This is the story of how we standardized source maps and how we continue to ship features through standards 📜 🧵

A JSON file representing a source map. The code contains:

{
"version": 3, // Always the integer 3
"file": "out.js", // Optional: name of the generated file
"sourceRoot": "", // Optional: prefix prepended to each entry in "sources"
"sources": ["foo.js", "bar.js"], // Required: list of original source URLs/paths (or null)
"sourcesContent": [null, null], // Optional: inlined source text, aligned with "sources"
"names": ["src", "maps"], // Optional: symbol names referenced by "mappings"
"mappings": "A,AAAB;;ABCDE", // Required: encoded mapping data (base64-VLQ deltas)
"ignoreList": [0] // Optional: indexes into "sources" considered "third-party"

Two years ago I interviewed a 31-year-old NY state assemblymember about a 7-year-old girl killed by an SUV driver in his district. I hung up the phone, astonished that I'd talked to a legislator who so thoughtfully articulated what actually needs to change on our streets. He'll make a great mayor

In February, 7-year-old Dolma Naadhun was crossing the intersection of Newtown Road and 45th Street in Astoria with her mother and sister when the driver of a 2021 Ford Explorer blew through a stop sign, striking and killing Dolma. One month later, New York City Department of Transportation commissioner Ydanis Rodriguez visited the crash site with other officials, met with community members demanding a traffic signal be installed, and promised to make changes to the street - including "daylighting"
the intersection using curb extensions and plastic bollards. State assemblymember Zohran Mamdani also visited the scene that day and realized that something else needed to change. "When you take a step back and think about traffic violence in New York City," he said, "you start to understand that this is a systemic issue that is incentivized by the policies that we have in place with regard to the design of our streets and what kind of vehicles we allow to be on our roads." Whether a driver runs a stop sign or a red light, statistically, certain cars - namely, bigger SUVs and trucks - are more likely to kill a 7-year-old. This is why Mamdani is co- introducing legislation for a weight-based vehicle-registration fee
intended to discourage people from purchasing heavier vehicles. "The car industry is pushing the sale of heavier and larger vehicles," he says. "The state has to make it clear that these types of vehicles
come with a certain kind of cost."

soar above adult shoulders. But there may be another way to disincentivize the purchases of such vehicles, says Edwards. "One other potential idea would be for someone, maybe a city's DOT, to start keeping a list of the different makes and models of vehicles that are killing pedestrians and cyclists, or kids specifically, and post that publicly," he says. "That could bring awareness to which cars are more dangerous and also potentially affect insurance rates,
which would possibly convince people not to buy certain cars." There's a bit of accountability in New York's bill, which would
require the State DOT to track all fatal crashes by vehicle weight. But the other encouraging aspect of the proposal is that the collected fees stay local, by county, and, after the annual dedications to highway, bridge, and transit trust funds are met, a full 75 percent of the funds raised will go toward safety
improvements like bike lanes, bollards, road diets, pedestrianization of streets, and raised crosswalks. This means the neighborhoods most impacted by large vehicles are likely to see the biggest changes. And that might be the most important part of the legislation, says Mamdani. "This is an initiative to make our streets safer for our children," he says. "And we are making sure a significant portion of this funding goes toward creating the very
streetscapes that we know will save their lives."
