TypeScript error when using with Vitest + Next.js and "skipLibCheck": false

[elliottsj]

Next.js uses "target": "es5" due to reasons described here.

So next build fails due to a type error when tinybench is present via Vitest:

../../node_modules/.pnpm/tinybench@2.1.5/node_modules/tinybench/dist/index.d.ts:254:5
Type error: Private identifiers are only available when targeting ECMAScript 2015 and higher.

  252 |  */
  253 | declare class Bench extends EventTarget {
> 254 |     #private;
      |     ^
  255 |     signal?: AbortSignal;
  256 |     warmupTime: number;
  257 |     warmupIterations: number;

I have "skipLibCheck": false, so setting "skipLibCheck": true would be a workaround, but I'd lose type safety.

Thanks for the notice! It should work now.
