Utils to remove repeated items from array & to sort based on equality

array-utils.ts

const getEqualitySorter =
  <T = unknown>(sortList: T[]) =>
  (a: T, b: T): number => {
    for (const i in sortList) {
      const orderItem = sortList[i];

      if (a === orderItem && b !== orderItem) return -1;
      if (a !== orderItem && b === orderItem) return 1;
    }

    return 0;
  };

const removeRepeated = <T = unknown>(arr: T[]): T[] =>
    arr.reduce<T[]>((a, b) => {
      if (!a.includes(b)) a.push(b);
      return a;
    }, []);

const data = parameter.map((p) => Object.keys(p)).flat();

console.log("initial data", data);
/* initial data [ 'type', 'name', 'default', 'description', 'type', 'name', 'description' ] */

console.log("parsed data", parsedData);
/* parsed data [ 'name', 'type', 'default', 'description' ] */
