Restrictive filtering array in Javascript/TypeScript for a relationship path problem

Question

I have a filtering problem I am trying to solve in TS/JS and stuck.

I want to filter an array with possible paths with an array of keywords. And it should not have any thing else other than these keywords.

let paths = ['Domain.travelers', 'Domain.travelers.products', 'Domain.travelers.remarks.products', 'Domain.products', 'Domain.vehicle.travelers.products'];
    
let keywords = ['travelers', 'products'];

When filter is applied, it should only return:

['Domain.travelers', 'Domain.travelers.products', 'Domain.products']

Answer 1

You can find docs about functions I used here:

• Array - MDN
• String - MDN

const paths = ['Domain.travelers', 'Domain.travelers.products', 'Domain.travelers.remarks.products', 'Domain.products', 'Domain.vehicle.travelers.products'];

const keywords = ['travelers', 'products'];

const results = paths.filter(path =>
  path.split('.').slice(1).every(
    pathPart => keywords.includes(pathPart)
  )
);

console.log(results);
