JavaScript

JavaScript (JS) is a lightweight interpreted or JIT-compiled programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB and Adobe Acrobat. JavaScript is a prototype-based, multi-paradigm, dynamic language, supporting object-oriented, imperative, and declarative (e.g. functional programming) styles.

That probably shouldn't be the property "columnNumber" for promise_index, which is used above, unsurprisingly, for columnNumber.
While I'm here, __callSiteEvals is a Deno thing? I didn't find a reference to it anywhere else online.

In my component's props TS interface, I can use JSDoc comments to set the description, and can even use the @default
tag to describe the default value
However, nothing happens when I use the @deprecated
tag.

What problem does this feature solve?
It would allow us to use numbers which is larger than MAX_SAFE_INTEGER.
What does the proposed API look like?
In HTML,
{{BigInt("100")}}
,{{100n}}
,{{2n * 50n}}
or{{50n + 50n}}
should show "100" (it can be just simply string by using .toString()) at frontend.At the moment using BigInt in "Mustache" syntax just throw error.
Sure, backu
