Removing package name from AndroidManifest.xml is required for RN 0.73. Libraries is started to remove it and switched to namespace since RN 0.71. You have 2 options:

React Native: A JavaScript Framework for Building Native Mobile Apps

Before you dive into the various aspects of building a JavaScript web app, it is important to get familiar with the language of the web - JavaScript, or ECMAScript. JavaScript is an incredibly versatile language which you can also use to build web servers, native mobile apps and desktop apps.

there are a whole bunch of complaints here

Using a monorepo is growing in popularity - there is even an open proposal to migrate react-native repository to monorepo. Find out more about React Native monorepo on github.

React Native JSI is a core change in the re-architecture of React Native. This is a layer that offers “synchronous” communication between JavaScript and native code. It will be replacing the default react native bridge. (Source)

SASS(.scss) [ https://sass-lang.com ]

Traditionally CSS lacked features such as variables, nesting, mixins, and functions. This was frustrating for Developers as it often led to CSS quickly becoming complex and cumbersome. In an attempt to make code easier and less repetitive CSS pre-processors were born. You would write CSS in the format the pre-processor understood and, at build time, you'd have some nice CSS. The most common pre-processors these days are Sass, Less, and Stylus. Any examples I give going forward will be about Sass as that's what I'm most familiar with.

CSS stands for Cascading Style Sheets, and is a scripting language used to style web pages. SCSS stands for Syntactically Awesome Style Sheet, and is a superset of CSS. You can think of SCSS as the more advanced version of CSS, which comes with several features that CSS does not support, such as the SCSS nested syntax, as shown below.

In the past, you’d need to rely on pre-processors such as SaSS or Less, but not anymore… Native CSS nesting has landed on all major modern browsers.

Sass is also a css preprocessor. Op is likely confused

sass -> An improvement over CSS. It provides nice features for managing CSS. good for mid-sized or even larger projects.

Sass (Syntactically Awesome Style Sheets) - A CSS preprocessor that simplifies and enhances your CSS workflow. Website: https://sass-lang.com/

Personally, my preference is Sass: I find that the mixins, partials, and operators are hugely useful when it comes to creating re-usable snippets of code for a design system. And, since it’s “just” a pre-processor and not a framework, it’s not opinionated in a design sense and there’s no default values (colors, spacing values, etc.) that will need to be overwritten.

Preprocessors: SSGs leverage preprocessors to streamline the development process. Preprocessors like SASS for CSS or Babel for JavaScript offer additional features and simplify code development.
