> --------------------------------------------------------------------------
>
> Key: FLINK-33938
> URL: https://issues.apache.org/jira/browse/FLINK-33938
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Web Frontend
> Affects Versions: 1.19.0
> Reporter: Ao Yuchen
> Assignee: Ao Yuchen
> Priority: Major
> Fix For: 1.19.0, 1.17.3, 1.18.2
>
>
> Since TypeScript 5.0, there is a break change that implicit coercions in
> relational operators are forbidden [1].
> So that the following code in
> flink-runtime-web/web-dashboard/src/app/components/humanize-date.pipe.ts get
> error:
> {code:java}
> public transform(
> value: number | string | Date,
> ...
> ): string | null | undefined {
> if (value == null || value === '' || value !== value || value < 0) {
> return '-';
> }
> ...
> }{code}
> The correctness improvement is availble in here
> [2][.|https://github.com/microsoft/TypeScript/pull/52048.]
> I think we should optimize this type of code for better compatibility.
