JavaScript: The Language That Powers the Web

JavaScript: The Language That Powers the Web
JavaScript is one of the most popular programming languages in the world, and for good reason. It's the language that powers the web, enabling developers to create interactive, dynamic websites and applications. Whether you're a beginner or an experienced developer, understanding JavaScript is essential for creating modern web experiences.

JavaScript is a versatile and powerful language that can be used for a wide range of tasks. It can be used to create interactive front-end web experiences, such as responsive navigation menus and image sliders, as well as more complex back-end web applications, such as e-commerce sites and social media platforms.



One of the most important features of JavaScript is its ability to manipulate the Document Object Model (DOM). The DOM is the way that JavaScript interacts with web pages, allowing developers to change the content, structure, and appearance of a web page based on user input or other events. This makes JavaScript an essential tool for creating dynamic, interactive web experiences.

Another key feature of JavaScript is its ability to interact with web servers and external APIs. This enables developers to create web applications that can retrieve and display data from other sources, such as social media platforms or weather services. This makes JavaScript a great choice for creating web applications that can access a wide range of data and services.

JavaScript also has a large and active community of developers, which makes it easy to find support and resources when you need them. There are countless libraries, frameworks, and tools that have been built to make it easier to work with JavaScript. Some examples of popular libraries and frameworks include React, Angular, and Vue.js. These tools provide developers with pre-built functionality and abstractions that can be used to speed up development and make it easier to build complex applications.

In conclusion, JavaScript is an essential tool for any developer looking to create modern web experiences. It's a versatile and powerful language that can be used for a wide range of tasks, and it has a large and active community of developers that make it easy to find support and resources when you need them. Whether you're a beginner or an experienced developer, understanding JavaScript is essential for creating interactive, dynamic websites and applications.

callback in javascript in hindi | callback function in javascript synchronous vs asynchronous

callback in javascript in hindi | callback function in javascript synchronous vs asynchronous.

In this video you will be learn callback function in javascript .

A callback function is a function passed into another function as an argument, which is then invoked inside the outer function to complete some kind of routine or action.

You can watch on video of Callback in javascript

now lets code to this
function printName(name) {
alert(`hi, ${name}`);
}

function useCallbackFun(callback) {
let name = prompt("Please enter your name.");
callback(name);
}

useCallbackFun(printName)

Now we create two function one is printName and seconod in useCallbackFun in this code we get the name in as argument in printName function and show to alert with text hi "name";


now in another way if we take time to get name then we used to this way to callback function

function printName(name) {
alert(`hi, ${name}`);
}

function useCallbackFun(callback) {
let name = '';
setTimeout(function(){
name = prompt("Please enter your name.");
callback(name);
},100)


}
useCallbackFun(printName)


Now let create another function with get odd and even number
as below is example :-


function isOdd(number) {
return number % 2 != 0;
}
function isEven(number) {
return number % 2 == 0;
}

function filter(numbers, fn) {
let results = [];
for (const number of numbers) {
if (fn(number)) {
results.push(number);
}
}
return results;
}
let numbers = [1, 2, 4, 7, 3, 5, 6];

console.log(filter(numbers, isOdd));
console.log(filter(numbers, isEven));
