Bug: Generic breaks code highlights

[RodrigoTomeES]

Hi,

Write a generic function break the code highlights, looks:

https://github.com/lukehaas/RunJS/assets/13077343/598ec768-af8b-4f4f-9ab9-abff12dcf74a

The code:

export const isNumber = <T,>(value: T): value is NonNullable<T> =>
  value !== '' &&
  typeof value !== 'object' &&
  typeof value !== 'boolean' &&
  !Number.isNaN(Number(value));

SO:

Version: 2.9.0 Config (is in spanish, I can't change the language of RunJS):

Seems to work fine for me (2.9.0):

[RodrigoTomeES]

Mmm I am also in 2.9.0. I update the issue with my config.

@RodrigoTomeES turn off the react-preset when this is on; it thinks you're writing JSX.

[RodrigoTomeES]

@lukehaas one question, as you said if I disable react-preset it works well but why react preset should break generic in TS? I use it in my .tsx files in vscode

[lukehaas]

It works in VS Code due to the comma before the closing bracket <T,>. Unfortunately, this is not supported in Codemirror.

[lukehaas]

Reopening as I will try and get this supported.

@RodrigoTomeES this is now resolved in the latest version of RunJS - version 2.10.0
