The window object is globally available in a JavaScript environment. It provides access to the browser window and its properties such as screen size, location, and history.
javascript
// Accessing current window width
const width = window.innerWidth;
The location object provides information about the current document's URL and enables navigation to other documents. It contains properties such as host, protocol, port, pathname, search, and hash.
javascript
// Accessing the current URL protocol
const protocol = window.location.protocol;
The navigate object allows us to manipulate the browser's history by moving forward or backward in the history stack.
javascript
// Going back one page
window.history.back();
The history object provides access to the browsing history and allows us to control navigation through the history stack.
javascript
// Checking if the previous page exists in the history
if (window.history.length > 1) {
// Go back one page
window.history.back();
}
The document object represents the current HTML document and provides access to its elements, styles, and events.
javascript
// Accessing the body element
document.body;
