filter array with multiple conditions by making use of destructuring

filterByConditions.ts

function filterByConditions(arr: any[], ...filterFunctionConditions: Function[]): any[][] {
  const results = [[]];
  filterFunctionConditions.forEach(() => results.push([]));
  for (const value of arr) {
    let conditionMet = false;
    for (let i = 0; i < filterFunctionConditions.length; i++) {
      if (filterFunctionConditions[i](value)) {
        results[i].push(value);
        conditionMet = true;
        break;
      }

    if (!conditionMet) {
      results[results.length - 1].push(value);
    }

const fruits = ['apple', 'orange', 'orange', 'apple', 'strawberry', 'banana', 'banana', 'raspberry'];
const conditions = [
  (val) => val === 'apple',

const [apples, oranges, bananas, otherFruits] = filterByConditions(fruits, ...conditions);

// [ 'apple', 'apple' ] [ 'orange', 'orange' ] [ 'banana', 'banana' ] [ 'strawberry', 'raspberry' ]
console.log(apples, oranges, bananas, otherFruits]
