AngularJS has data binding bundled in by default.
React is generally augmented by Redux to give unidirectional data flow and work with immutable data.

Nest is a framework for building efficient, scalable Node.js server-side applications. It uses progressive JavaScript, is built with TypeScript (preserves compatibility with pure JavaScript) and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming) Under the hood, Nest makes use of Express, but also, provides compatibility with a wide range of other libraries, like e.g. Fastify, allowing for easy use of the myriad third-party plugins which are available.. On the other hand, Node.js is detailed as "A platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications".

Props are arguments passed into React components.
const means that the identifier can't be reassigned.

M○|-|FΞY 🇳🇬 i recommend you react because:
Redux is far from dead or be killed by React Context. Redux is such a boilerplate and requires a bunch of libraries. ... Because, the React Context will trigger a re-render on each update, and optimizing it manually can be really tough. And there, a solution like Redux is much easier to implement.
