JavaScript - Detect ESC key cross browser

To detect the ESC key press event in JavaScript across different browsers, you can use the following code:

document.addEventListener("keydown", function(event) {
  if (event.key === "Escape" || event.keyCode === 27) {
    // ESC key was pressed
    // Your code here
  }
});

This code adds an event listener to the keydown event of the document object. When a key is pressed, the event object is passed to the callback function. The code inside the function checks if the pressed key is either "Escape" or has a key code of 27 (which corresponds to the ESC key). If the condition is true, you can add your code to be executed when the ESC key is detected.

This approach works across different browsers because it checks both the event.key property (which represents the actual key name) and the event.keyCode property (which represents the key code).

JavaScript is a widely used programming language for both front-end and back-end development. It is primarily used for adding interactivity and dynamic behavior to websites. JavaScript can be used to create interactive forms, validate user input, manipulate the DOM, make AJAX requests, and much more.
