Progressive Web Apps are easy to implement. You don't need to hire another app developers in order for you to have PWA. Because PWA uses only Javascript. So if you already have JavaScript developers, then you don't need additional developers if you want your business to create PWA.
PWA is an alternative for native apps. These applications are easy to develop and also budget friendly. Using PWA instead of developing hybrid apps will help a company to save development time and cost. Though not all browsers support PWAs, but then we are in a state of moving towards technological advancement. So we expect more tech companies will now support PWAs.
