On a side note, I really wish I could learn to tell exactly if a new feature like this is already supported in a project I'm working. babel.config.js is just a mistery to me. @babel/present-env, targets: { node: 'current' }, forceAllTransforms, useBuiltIns, 'corejs', modules, @babel/plugin-proposal-object-rest-spread. I mean, I generally dump it into Chat GPT and ask for an explainer, but... how can I know for sure I can use `array.reverse()` and it will be correctly handled in older browsers? And how does the babel version in yarn.lock relate to all this? What about the .browserslistrc which contains 'defaults' ? My god.
