Build A Weather App Using
HTML
CSS
JavaScript
Building a Weather app with JavaScript is an excellent project for beginners. It helps to understand the core basics of the DOM and teaches how to use fetch API, to call and get data from a third-party service.
In this tutorial, we'll be building a geolocation-based weather app that will show us the current weather data depending on the user's location.
