Node.js v18 & v19 don't support some es2023 features

[mdashlw]

ES2023 introduced toSorted, toReversed, toSpliced , with, and findLast and findLastIndex methods on Array.prototype,
Node.js 18 and 19 only support findLast and findLastIndex, and don't support toSorted and others

node18 and node19 bases both specify es2023 lib

I suspect nothing can be really done about this?

At this repo no, but those will probably come (or be fixed in) a new TypeScript release I expect

Filed microsoft/TypeScript#56796.

Maybe https://devblogs.microsoft.com/typescript/announcing-typescript-4-5-beta/#supporting-lib-from-node_modules can work to override es2023 (or just es2023.array if possible)?

I sent microsoft/TypeScript-wiki#343 to fix the wiki; my memory is bad so I can't remember why I changed Node18 to ES2023 but I don't think it's correct in retrospect.

(Maybe at that date, ES2023 hadn't been finalized? And so node.green did not include them?)
