Call Stack

Try guess the output without run the code!! Simple explanation How JavaScript code is executed internally. At first before executing the JavaScript code, It will create a global execution context and pushed into call Stack (from where code is executed). In global context it has two phase (memory reservation and…

Operating systems are complex pieces of software that require low-level hardware interaction and advanced memory management, among other things. Python is an interpreted language and does not have direct access to system-level resources, making it unsuitable for writing an operating system. However, we can explore how a call stack and…

To understand JavaScript language deeply, it's very important to know about its inner working structure. Execution context and the call stack are one of them. What is the Execution context? In a simple way, the execution context is the environment in which a piece of JavaScript code is executed. Stores…

The call stack is a fundamental concept in computer science, and it plays a crucial role in understanding how programs work. It is a data structure used by the runtime environment of a programming language to keep track of function calls. Whenever a function is called, the runtime environment pushes…

Stack overflow is a common software programming error that occurs when a program exceeds the maximum amount of memory that is allocated for its execution. This can happen when a program is written in a way that allows function calls to be repeated indefinitely, leading to a buildup of function…

The JavaScript call stack is a critical component of the JavaScript language and plays a crucial role in executing and processing our code. Understanding the call stack is essential for developers to effectively debug their code, improve performance, and write more efficient and maintainable code. In this blog, we will…

You might know that JavaScript is an asynchronous programming language that offers a lot of functionalities but at the same time, it’s single-threaded and non-blocking. You may be wondering how single-threaded language can execute asynchronous functionalities. So this article may clarify your doubts about this topic. What are Synchronous & Asynchronous? Before diving, into the…

The fact that Javascript code is executed by the javascript engine in conjunction with a runtime environment — either a web browser or Nodejs — allows it to run on virtually any device. The engine was used to execute the code line by line before Javascript made the decision to…

As you know, JavaScript is a single-thread language. So, It is really important to know how our codes will be running in JavaScript when we have some complicated codes and time-consuming functions. What will happen when a part of our codes may take a long time to complete? …
