Today, I created small application which is Weather app using html, css ,javascript and eact. And one important thik is we must have APIKEY and URL. If you want API key go official openweather app web and create a account then they provide only one the API key you will copy the key and use the key in your application. If you interested to creat a weather app.
Html,Css and JavaScript code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>
