 So I'm Rajat. I am a JavaScript and iOS developer. I work with the Drive Facts. Apart from that, I run my own startup, which is Poolmarite. It's a write sharing app. And I'm going to talk about Ionic framework today. So before we start, let's see what is the problem. Has it happened to you? You wake up in the morning and you get a very nice idea. And you think that, yes, I want to develop it to a mobile app. How many of you experienced that? That this is a major necessity. It has not been implemented yet. So we get those ideas every day. But then we go beyond that and we start thinking that, oh, we have to develop it on Android, iOS, Windows, which is a big market according to Microsoft, and web as well. So then you think further, oh, I need to hire freelancer developers or I have to hire my own company and start my own team. But that involves a lot of costs. If you don't want to do that, you are a full start developer. You want to do it on your own. You start making every platform app on your own. But that involves time. Until then, somebody would have copied your idea and published the app to the customers. This is, next to this is if you develop everything according to what you plan, you still need to write a lot of test cases and handle different test scenarios in each of the platforms. So after all this friction, ultimately, your idea reaches the audience. And the idea is not what you intended initially. It has some other, it is serving some other purpose. Or it has a lot of bugs on different platforms for different customer segments. So this is a major drawback of today's technology that you want to bootstrap an idea and it is way too difficult or it takes a lot of time. So what if you could combine everything into a single pipeline and bring it on a single language, single framework, and deploy it everywhere? That's what Ionic does. It gives you a single code base where you can write single test cases and distribute app among your testers or friends and then release it to public. So what is Ionic? Ionic is, I would say in a plain simple language, is combination of Angular and PhoneGap. If you have heard of PhoneGap, PhoneGap is kind of a framework which bridges a web view to the native features of your mobile phone SDKs. So they did a good part, like they started fine.
