Some time−consuming tasks are executed without blocking the main thread in Asynchronous programming. In certain cases, developers may need to delay the execution of a loop to control the flow of their program or introduce delays between iterations. JavaScript provides several techniques for delaying execution, and in this article, we will explore how to delay a loop using the combination of async/await and Promises. Understanding async/await The async/await syntax was introduced in ECMAScript 2017 (ES8) and provides a concise and readable way to write asynchronous code. It is built on top of Promises and allows developers to write asynchronous code ... Read More

JavaScript is a widely used programming language for creating interactive and dynamic web applications. However, like any other programming language, JavaScript code can contain bugs that may lead to unexpected behavior or errors. Debugging is the process of identifying and fixing these issues. In this article, we will explore different methods to debug JavaScript files. Method 1:Console.log() Method The simplest and most commonly used debugging technique is the console.log() method. By inserting console.log() statements at strategic points in your code, you can output specific values and track the flow of execution. Syntax console.log(value1, value2, ..., valueN); Here, the ...
