JavaScript web APIs (such as Fetch, Web Storage, Geolocation)

JavaScript web APIs are a set of APIs provided by web browsers that allow web developers to access certain functionality and information from within a web page. Some of the most commonly used JavaScript web APIs include:

  • Fetch API: The Fetch API provides a simple interface for fetching resources over the network, such as HTTP requests. It's a modern alternative to XMLHttpRequest (XHR) and offers a more straightforward syntax for making network requests.

  • Web Storage API: The Web Storage API provides a way to store data in the browser, either in local storage (persistent) or session storage (temporary). This API is useful for storing information that needs to persist across page refreshes or multiple visits to the website.

  • Geolocation API: The Geolocation API provides access to the device's geographic location. This information can be used to provide location-based services, such as maps or weather reports. The API can access the device's GPS or other location sources, with the user's permission.

These APIs allow web developers to build rich and interactive web applications that can access device information, make network requests, and store data in the browser. Understanding and being proficient in these APIs is an important part of modern web development and is essential for building advanced and feature-rich web applications.
