It looks like you've sent a pull request to update our 'lib' files. These files aren't meant to be edited by hand, as they consist of last-known good states of the compiler and are generated from 'src'. Unless this is necessary, consider closing the pull request and sending a separate PR to update 'src'. |

@andrewbranch should be good now |
|
I get why it’s happening and I guess it technically makes sense, but I feel like the baseline changes look kind of confusing and undesirable. |
|
Just out of curiosity @typescript-bot perf test this |

so i fixed it by using the i'll make a PR to definitelytyped with this change later today and link it here |
|
My biggest concern right now is that it might be confusing to some users for the quick info / errors for every common Array method to reference |
|
i personally don't think that's an issue. most other languages have a base "collection" or "iterable" interface that mutable arrays extend. i'd argue that it's far more confusing now than it would be after this change. currently it's difficult to even tell if currently the only way to find out is by attempting to use an however if you think the name interface BaseArray<T> {
map<U>(callbackfn: (value: T, index: number, array: this) => U, thisArg?: any): U[];
filter<S extends T>(predicate: (value: T, index: number, array: this) => value is S, thisArg?: any): S[];
//...
}
export interface ReadonlyArray<T> extends BaseArray<T> {
//nothing to see here
}
export interface Array<T> extends ReadonlyArray<T> {
push(...items: T[]): number;
//...
} |

@DanielRosenwasser i ran the same command mentioned in that PR with and without my change, and as far as i can tell there doesn't seem to be much of a difference: before: after: (disclaimer: my PC is not good and it was difficult to get consistent results) |
