'this' in functional vs arrow function in javascript

on

 The arrow function cannot be invoked with the new keyword, because arrow functions don’t have a constructor. If you try to instantiate with a new keyword it will throw an error.

No own this (call, apply & bind won’t work as expected)

In a traditional function, its internal this value is dynamic, it depends on how the function is invoked. For example:

Unlike regular functions, arrow functions don’t have their own this binding. If we access this in the arrow function it will return the this of the closest non-arrow parent function.

The value of this in the arrow function is determined at the time of declaration and never changes. So call, apply, bind cannot change the value of the arrow function this.

Why "F" and "L" suffix | (10.0F, 10L)

on
Let us take it this way, We will create their needs. So we will get why they are needed. Try to guess, which functions will be executed in the following program: public class MyClass {     public static void main(String args[]) {         MyClass obj = new MyClass();         obj.fun1(10);     }     void fun1(byte val){         System.out.println(val);     }     void fun1(int val){         System.out.println(val);     }     void fun1(float val){         System.out.println(val);     }     void fun1(long val){         System.out.println(val);     }     } It seems like every method is capable to run this program because 10 is still literal because It has no data type. Before Java, In previous technologies, this scenario gave an ambiguity...

Promises and Async-await in depth : Asynchronous Programming in Javascript

on
Promises and Asynchronous Programming One of the most powerful aspects of JavaScript is how easily it handles asynchronous programming. As a language created for the Web, JavaScript needed to be able to respond to asynchronous user interactions such as clicks and key presses from the beginning. Node.js further popularized asynchronous programming in JavaScript by using callbacks as an alternative to events. As more and more programs started using asynchronous programming, events and callbacks were no longer powerful enough to support everything developers wanted to do.  Promises  are the solution to this problem. Promises are another option for asynchronous programming, and they work like futures and deferreds do in other languages. A promise specifies some code to be executed later (as with events and callbacks) and also explicitly indicates whether the code succeeded or failed at its job. You can chain promises together based on success or failure in ways that make your code...

ChatGPT aur Google me kya difference hai?

on
  ChatGPT aur Google dono alag-alag hain. ChatGPT ek language model hai jo ki OpenAI dwara train kiya gaya hai. Iski madad se hum natural language text ko generate, understand, aur respond kar sakte hain. Google, on the other hand, ek search engine hai jo ki internet par available information ko search karne ki capability rakhta hai. ChatGPT language model ke through hum natural language text ko generate kar sakte hain, jese ki poetry, stories, articles and so on. Iski madad se hum human-like text ko generate kar sakte hain. Google, on the other hand, internet par available information ko search karta hai. Iske through hum kisi bhi topic ke bare me jankari le sakte hain. Dono alag hain, lekin kuch similarities bhi hain. Dono natural language text ke sath work karte hain. ChatGPT natural language text generate karne ke liye use kiya jata hai, aur Google natural language text ko search karne ke liye use kiya jata hai. ChatGPT ke through hum natural language text ko generate kar sakte...
