In the old version of JavaScript, bind is often used to explicitly set the point of this. This mode can usually be found in some early versions of the framework (such as React) before the emergence of ES6. The emergence of arrow functions provides a more convenient way to solve this pro...
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 ...

What's more, you can create functions that are flexible about the number of parameters they accept. This is possible thanks to the arguments array that is created automatically inside each function. Here's a function that simply returns whatever parameters are passed to it:...
A JavaScript library is a collection of pre-written code that performs certain functions. Libraries allow even novice users to build useful websites quickly. And they save both novice and experienced users significant time in building sites and applications. While there are many JavaScript libraries,...
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...
Decorator factoriesare functions that return decorator functions. Instead of defining a decorator directly, we create a function that generates decorators based on the arguments we pass. This makes it possible to customize the behavior of decorators, making them highly versatile and reusable. ...
