Higher-Order Components (HOCs) are a powerful pattern in React.js that allows you to reuse component logic. HOCs are functions that take a component as an argument and return a new component with enhanced functionality. They are used for cross-cutting concerns such as code reuse, logic abstr...
Functional Programming:JavaScript supportsfunctional programmingconcepts like higher-order functions, pure functions, immutability, and function composition. It provides built-in functions likemap(), reduce(),andfilter()that can be used in a functional programming style. Event-Driven Programming:JavaScript ...
Node.JS makes use of the non-block I/O system, which is optional. Higher priority is given to requests with quick responses. In comparison to Python or Ruby on Rails, your web applications will run faster thanks to this preference order. As Node.JS is dependent on JavaScript, it is simp...

Functional Programming: JavaScript also supports functional programming concepts, such as higher-order functions and closures, which can make it easier to write complex applications. Event-Driven Programming: JavaScript is designed to be event-driven, which means that it can respond to user actions, ...
Closures and higher-order functions.Closures are functions that retain access to their lexical scope, even when executed outside that scope. Higher-order functions are functions that take other functions as arguments or return them as results. These features enable powerful patterns for abstraction and...
What are the new features and their practical use cases? Aside from a single, butimportant, breaking change, Node.js 15 is mainly about new features. Updating from older Node.js versions should therefore be fairly straightforward. Keep in mind that Node.js 15 won't go into LTS, more on ...
In computing and programming, a framework provides a structure on which new software programs and applications can be built. A framework may be for a set of functions in a system and how they interrelate; the layers of an operating system or an application subsystem; or how communication shoul...
