How do I filter an array with TypeScript in Angular?

Question

I have this code

// Common
import { Pipe, PipeTransform } from '@angular/core';

// Interface
import { IQuestion } from '../../models/question.interface';

@Pipe({
  name: 'tableFilter',
})
export class TableFilterPipe implements PipeTransform {
  transform(list: Array<IQuestion>, value: string) {
    const filterWords: Array<string> = value
      .split(/[. ,;\\\/]/)
      .filter((word) => {
        const isNumber: boolean = Number.isInteger(Number(word));
        const isAvailableLength: boolean = word.length > 2;
        const isLk: boolean = /^ЛК$/i.test(word);

        if (isNumber || isAvailableLength || isLk) {
          return true;
        }
      })
      .map((word) => word.slice(0, 3).toLowerCase());

    return value
      ? list.filter((tableRow) => {
          const isEveryWordExistInQuestion: boolean = filterWords.every(
            (word) => tableRow.question.toLowerCase().includes(word)
          );

          const isEveryWordExistInAnswer: boolean = filterWords.every((word) =>
            tableRow.answer.toLowerCase().includes(word)
          );

          const isEveryWordExistInNumber: boolean = filterWords.every(
            (word) =>
              tableRow.category.number.toString() === word ||
              tableRow.product.number.toString() === word ||
              tableRow.number.toString() === word
          );

          if (
            isEveryWordExistInQuestion ||
            isEveryWordExistInAnswer ||
            isEveryWordExistInNumber
          ) {
            return true;
          }

          return false;
        })
      : list;
  }
}
