A way to process an array via map and filter by passing an array of maps and filters

exampleArrayProcessor.js

function buildArrayProcessorChain (rawArrayProcessors) {
  const arrayProcessors = (typeof rawArrayProcessors !== "object" ? [] :
    Array.isArray(rawArrayProcessors) ? rawArrayProcessors : [rawArrayProcessors])
    .filter(v => (v.map === undefined && typeof v.filter === "function") || (v.filter === undefined && typeof v.map === "function"));

  if (arrayProcessors.length === 0) return (a) => a; // nothing to do

  return arrayProcessors.reduceRight((p, c) => {
    // filter
    if (typeof c.filter === "function") return (a) => typeof p !== "function" ? Array.prototype.filter.call(a, c.filter) : p(Array.prototype.filter.call(a, c.filter));

    // map
    if (typeof c.map === "function") return (a) => typeof p !== "function" ? Array.prototype.map.call(a, c.map) : p(Array.prototype.map.call(a, c.map));

    // invalid item, skipping
    return (a) => typeof p !== "function" ? a : p(a);
  }, {});
}

function main() {
  const a = {
    name: "Has City",
    filter: (v) => {
      Logger.log("City? %s", v.city);
      return v?.city?.length > 0;
    }
  };
  const b = {
    name: "Under 52",
    filter: (v) => {
      Logger.log("52> %s", v.age);
      return v?.age <52;
    }
  };
  const c = {
    name: "Uppercase Names",
    map: (v) => {
      v.name = v.name.toUpperCase();
      Logger.log("BIGNAME %s", v.name);
      return v;
    }
  };
  const d = {
    name: "No names with upper O",
    filter: (v) => {
      const remove = v?.name.match(/O/);
      Logger.log("Big O is NO %s, %s", v.name, !remove);
      return !remove;
    }
  };

  const fns = [a,b,c,d];
  const procs = buildArrayProcessorChain(fns);

  if (typeof procs === "function") Logger.log(procs([
    {
      name: "Alice",
      age: 40,
      city: "Dallas",
    },
    {
      name: "Bob",
      age: 52,
      city: "Chicago",
    },
    {
      name: "Connie",
      age: 28,
      city: "Portland",
    },
    {
      name: "Debra",
      age: 61,
      city: "Seattle",
    },
    {
      name: "Edna",
      age: 14,
      city: "Salt Lake City",
    },
  ]));
}
