- JavaScript: Do not format functions with arguments as react hooks ([#5778] by [@SimenB])
The formatting added in Prettier 1.16 would format any function receiving an
arrow function and an array literal to match React Hook's documentation.
Prettier will now format this the same as before that change if the arrow
function receives any arguments.
```js
// Input
["red", "white", "blue", "black", "hotpink", "rebeccapurple"].reduce(
(allColors, color) => {
return allColors.concat(color);
},
[]
);
// Output (Prettier 1.16.0)
["red", "white", "blue", "black", "hotpink", "rebeccapurple"].reduce((
allColors,
color
) => {
return allColors.concat(color);
}, []);
// Output (Prettier 1.16.1)
["red", "white", "blue", "black", "hotpink", "rebeccapurple"].reduce(
(allColors, color) => {
return allColors.concat(color);
},
[]
);
```
- JavaScript: Add necessary parentheses for decorators ([#5785] by [@ikatyang])
Parentheses for decorators with nested call expressions are optional for legacy decorators
but they're required for decorators in the current [proposal](https://tc39.github.io/proposal-decorators/#sec-syntax).
```js
// Input
class X {
@(computed().volatile())
prop
}
// Output (Prettier 1.16.0)
class X {
@computed().volatile()
prop
}
// Output (Prettier 1.16.1)
class X {
@(computed().volatile())
prop
}
```
- TypeScript: Stable parentheses for function type in the return type of arrow function ([#5790] by [@ikatyang])
There's a regression introduced in 1.16 that
parentheses for function type in the return type of arrow function were kept adding/removing.
Their parentheses are always printed now.
```ts
// Input
const foo = (): (() => void) => (): void => null;
const bar = (): () => void => (): void => null;
// First Output (Prettier 1.16.0)
const foo = (): () => void => (): void => null;
const bar = (): (() => void) => (): void => null;
// Second Output (Prettier 1.16.0)
const foo = (): (() => void) => (): void => null;
const bar = (): () => void => (): void => null;
// Output (Prettier 1.16.1)
const foo = (): (() => void) => (): void => null;
const bar = (): (() => void) => (): void => null;
```
- MDX: Correctly recognize inline JSX ([#5783] by [@ikatyang])
Previously, some inline JSXs are wrongly recognized as block HTML/JSX,
which causes unexpected behaviors. This issue is now fixed.
```md
_foo bar_
_foo
bar_
_foo bar_
