Hi all! Hope it helps... Here are some interesting cases with Pipeline tap operator |:

case1: Pipeline tap operator |: and Ternary Comparison Assignment Operators:
const result = someData
  |> someData.filter(x => x >= 10) ? "true" : "false";
case2: Pipeline tap operator |: and Optional Primitive Type Annotation and Ternary Comparison Assignment Operators and Ternary-like try/catch:
function test1(a: string): string {
    return a.toUpperCase();
}

const result = someData
  |> someData.filter(x => x >= 10) try? test1('value1'): "false"; // if sucess call test1 ... catch "false"
case3: Pipeline tap operator |: and Concurrent Async and Normal Await Evaluation Blocks and Ternary-like try/catch:
const data = {
  x: awaitmulti getX(),
  y: await.multi getY(),
}

const result = data
  |> data.filter(x => x >= 10) try? "true": "false"; // if sucess  true  ... catch "false"
case4: Pipeline tap operator |: and Class property parameters
class DataStorage {
  constructor(this value) {}
}

const result = someData
  |> someData.filter(x => x >= 10) ? DataStorage(x) : "false";
