Custom RxJS Operators are Standing By! Act Now!
summary
Shows how to build custom RxJS operators by composing existing RxJS primitives with the pipe function and tests each operator in isolation including marble timing tests; refactors an autocomplete observable into named operators limitResults filterExistingTeamMembers and throttleInput; builds a Pokemon team autocomplete demo (poketeambuilder.pirko.dev) and replaces five-plus operator chains with single calls so the component shrinks and unit tests verify behavior end to end.
