var data=[{type:"parent-category",order:1,categoryId:1},{type:"parent-category",order:2,categoryId:2},{type:"child-category",order:1,categoryId:3,parentCategoryId:1},{type:"child-category",order:2,categoryId:4,parentCategoryId:1},{type:"child-category",order:2,categoryId:5,parentCategoryId:2},{type:"child-category",order:1,categoryId:6,parentCategoryId:2}]

let res = data
  .filter(({type}) => type === "parent-category")
  .sort((a,b) => a.order - b.order)
  .reduce((acc, curr) =>{
    const children = data
      .filter(({parentCategoryId}) => parentCategoryId === curr.categoryId)
      .sort((a,b) => a.order - b.order);

    acc.push(curr, ...children);
    return acc;
  }, []);

console.log(res);
