Nest.js is a scalable, server-side JavaScript framework built with TypeScript that still preserves compatibility with JavaScript. You’ll approach this project by separating the application into two different sections: the frontend and the backend. You’ll use Nest.js to build the backend, Vue.js for the front-end application, and MongoDB to persist your app’s data.
Machine learning is a research field in computer science, artificial intelligence, and statistics. The focus of machine learning is to train algorithms to learn patterns and make predictions from data. Machine learning is especially valuable because it lets us use computers to…
The Web Speech API grants developers the ability to create text-to-speech apps for a web browser. In this tutorial, you will use the Web Speech API to build a text-to-speech app.
Progressive web apps are web applications built with technologies that make them behave like native apps. A benefit of progressive web apps is the ability to work smoothly when network coverage is unreliable. In this article, you’ll build a progressive web app with Angular and deploy it with Firebase.
In computer programming, loops allow us to automate and repeat similar tasks multiple times. In this tutorial, we’ll be covering how for loops work in Python and how to construct them.
