How to write an ios application using js and html?

Question

JavaScript

I came up with a not very complicated application that is the fastest way to do it on html and js.
How to make such an application and how to place it. Share your experience.
It is also not necessary, but it is desirable that the application has the following functionality.
- notifications pop up like whatsapp or viber with a new message when the screen
is locked - a number about a new message appears on the application icon
- the application must send ajax or somehow work with the server exchanging json
- well, inside the application should load pictures from the server and not store them inside myself
And another counter question
If I study the development of a full application, then I will need a poppy axis, but I am not ready to spend money on a computer now.
Is there an option to install a macOS on an emulator and develop full-featured applications by downloading them on the app store?
Or is there something that won't work?
Thanks for your detailed answers ;)

1. If absolutely js and html - phonegap to help
2. If you want something more decent, with a native interface, but also on js - https://www.nativescript.org/
From your list of requirements, both can do everything, but there is a question with a number on the icon. You can definitely implement it with NS, but it’s easier to learn Swift
3. Learn Swift - look at the swiftbook.ru/doc documentation, it is very similar in syntax to ES6 (and even more to TypeScript). This path does not seem so difficult to me, after I ran through the documentation with my eyes.
About Hackintosh - I heard that the assembly from Niresh is the most painless in the installation. If you put it - write in the comments how it is. There shouldn't be any problems with uploading to the AppStore - at the last job, iOSers sat on Hackintosh and cried, but ate the cactus.

Apache Cordova or Node-Webkit from Intel. Both in parallel allow you to collect for both Android and iOS.
There are examples of pretty fancy commercial toys built on these instruments.
Development can be carried out in any environment, debugged on a simulator or iPhone, a Mac machine is not required at all.
