TypeScript

TypeScript is an open source programming language developed by Microsoft and first released in 2012. It is designed to add type safety to JavaScript while conforming as closely as possible to the syntax and semantics of the ECMAScript standard.
It is a syntactical superset of the JavaScript programming language; all valid JavaScript source code is also valid TypeScript source code, but not vice-versa. TypeScript compiles (or transpiles) to JavaScript, meaning that it can be utilized to target any JavaScript environment. It can be used to develop JavaScript for both client-side and server-side applications.

ES imports and exports can only be used at the top level of a module. This is illegal:
function container() {
import 'fs'
export { container }
namespace N { }
}
The current error for these three statements are vague and, for JS, contain irrelevant terms:
Actual:
(1) "An import declaration can only be used in a namespace or module."
(2) "An export declaration can

Current behavior 😯
The text inside of a button with size="small"
is not centered vertically. This is especially obvious when used with an icon or a contained/outlined button.
Expected behavior 🤔

Describe the bug
In Firefox, the zoom feature uses transform
styles (see storybookjs/storybook#12845) - unfortunately this breaks positioning on elements that require position: fixed
when in the "Docs" view.
Normally a position: fixed
element's position would correspond to the viewport but in Firefox it corresponds to the element with the transform
style.

I'm making a client-side code editor with rudimentary Git support, and syntax highlighting for diff/patch files would be really nice - a way to view the whole diff in a single window (alternative to existing diffeditor - with similar colors to git diff
console coloring), maybe would be useful for others too.

The documentation for mutate
talks about local mutation for faster feedback, but the documented way to use it only mutates after a promise has resolved - in other words, not immediately.
As a result, I've found myself writing code in this kind of pattern:
mutate(path, { ...data, patch }, false); // mutate immediately, don't revalidate
await patchData(patch); // await the

How to reproduce
