In this tutorial we will learn to close the browser window using JavaScript. Suppose a user has your website open in 2 tabs and doesn't want to allow it, then you can use JavaScript to automatically close one tab.
Also, if you notice that some web applications automatically open a browser window to capture a face, it will automatically close when you capture the image by clicking the button. That's all we can do with JavaScript.
This tutorial will teach different examples of using JavaScript to close the current tab in a browser window.
NOTE - JavaScript never allows developers to close windows opened by the user. This is due to some security issues. Therefore, programmers can only close the browser window opened using JavaScript's open() method.
grammar
You can use the close() method to close the browser window according to the following syntax.
let new_window = window.open(URL, width, height); new_window.close();
In the above syntax, we store the return value in the new_window variable when we create it. After that, we close the newly opened window using the close() method.
Example
In this example, we have two buttons; one opens a new tab and the other closes the new tab opened using JavaScript.
The user first needs to open the tab using JavaScript by clicking the "Open New Tab" button. They can click the "Close New Tab" button and watch it automatically close the tab.
<html> <body> <h2 id="Using-the-i-window-close-i-method-to-close-the-browser-s-tab">Using the <i>window.close()</i> method to close the browser's tab</h2> <p>Click "Open New Tab" to open a page in new tab and click "Close New Tab" to colse the opened tab</p> <button id = "openTab" onclick = "openTab()">Open New Tab </button><br><br> <button id = "closeTab" onclick = "closeTab()">Close New Tab</button> <script> // creating the variable to store the tab var new_tab; function openTab() { // open a new tab new_tab = window.open("https://www.tutorialspoint.com/answers/shubham-vora"); } function closeTab() { // close tab new_tab.close(); } </script> </body> </html>
Example
In the example below, we have created two buttons like the example above to open and close the tab. However, in this example, we have also added "_blank" as a parameter to the open method, which will open a new window instead of a new tab.
Next, the user can click the new window button to close the pop-up window.
<html> <body> <h2 id="Using-the-i-window-close-method-i-to-close-the-browser-s-window">Using the <i>window.close() method</i> to close the browser's window.</h2> <p>Click "Open New Window" to open the page in new window and click "Close New Window" to colse the opened window</p> <button id = "openWidnow" onclick = "openWindow()"> open new Window</button><br><br> <button id = "closeWidnow" onclick = "closeWindow()">Close new Window</button> <script> // creating the variable to store window var new_window; function openWindow() { // open a new window new_window = window.open("https://www.tutorialspoint.com/index.htm", "_blank", "width=800"); } function closeWindow() { // close the window new_window.close(); } </script> </body> </html>
Thus, users learn to use JavaScript to open new tabs or windows. Additionally, you learned to use the close() method to close a tab or window.
In addition, we can also open a new window to accept user input. When the user submits the form data, we can call the close() method in the function that processes the form data.

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.

The power of the JavaScript framework lies in simplifying development, improving user experience and application performance. When choosing a framework, consider: 1. Project size and complexity, 2. Team experience, 3. Ecosystem and community support.

Introduction I know you may find it strange, what exactly does JavaScript, C and browser have to do? They seem to be unrelated, but in fact, they play a very important role in modern web development. Today we will discuss the close connection between these three. Through this article, you will learn how JavaScript runs in the browser, the role of C in the browser engine, and how they work together to drive rendering and interaction of web pages. We all know the relationship between JavaScript and browser. JavaScript is the core language of front-end development. It runs directly in the browser, making web pages vivid and interesting. Have you ever wondered why JavaScr

Node.js excels at efficient I/O, largely thanks to streams. Streams process data incrementally, avoiding memory overload—ideal for large files, network tasks, and real-time applications. Combining streams with TypeScript's type safety creates a powe

The differences in performance and efficiency between Python and JavaScript are mainly reflected in: 1) As an interpreted language, Python runs slowly but has high development efficiency and is suitable for rapid prototype development; 2) JavaScript is limited to single thread in the browser, but multi-threading and asynchronous I/O can be used to improve performance in Node.js, and both have advantages in actual projects.

JavaScript originated in 1995 and was created by Brandon Ike, and realized the language into C. 1.C language provides high performance and system-level programming capabilities for JavaScript. 2. JavaScript's memory management and performance optimization rely on C language. 3. The cross-platform feature of C language helps JavaScript run efficiently on different operating systems.

JavaScript runs in browsers and Node.js environments and relies on the JavaScript engine to parse and execute code. 1) Generate abstract syntax tree (AST) in the parsing stage; 2) convert AST into bytecode or machine code in the compilation stage; 3) execute the compiled code in the execution stage.

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.
