Consider switching to dequal

[jelly]

This doesn't help us a lot but dequal is a 14 kB library versus deep-equal which is 90 kB, however has 16 dependencies while dequal has zero. So in the end it might help if other deps drop those dependencies as well.

https://www.npmjs.com/package/dequal

Oh, nice idea! We even already have dequal in our tree, although only a dev dep:

dequal@2.0.3 dev
node_modules/dequal
  dequal@"^2.0.3" from axobject-query@3.2.1
  node_modules/axobject-query
    axobject-query@"^3.2.1" from eslint-plugin-jsx-a11y@6.8.0
    node_modules/eslint-plugin-jsx-a11y
      dev eslint-plugin-jsx-a11y@"6.8.0" from the root project
  dequal@"^2.0.3" from aria-query@5.3.0
  node_modules/aria-query
    aria-query@"^5.3.0" from eslint-plugin-jsx-a11y@6.8.0
    node_modules/eslint-plugin-jsx-a11y
      dev eslint-plugin-jsx-a11y@"6.8.0" from the root project

We also already have https://www.npmjs.com/package/fast-deep-equal as devDependency, also via eslint. But I agree that dequal/lite seems enough for our purposes. https://unpkg.com/dequal@2.0.3/lite/index.mjs really looks quite nice 😁

@jelly do you want to give this a shot?

dequal/lite seems interesting, note that deep-equal is a bundled dependency and sadly axobject-query will soon no longer pull dequal after this PR A11yance/axobject-query#354

I'm happy to take a look at this during the pilot shift.
