The Axios HTTP client library is used to perform a straightforward HTTP GET request in order to first acquire the website's HTML. The asynchronous method getPostTitles() will browse the archived r/programming forum on Reddit. Placing a simple web server as shown below: Therefore, NodeJS is a runtime environment that enables the server-side execution of JavaScript-written applications.Ĭontrary to how other languages, including C and C++, handle concurrency, NodeJS uses a single main thread and makes use of it to carry out activities in a non-blocking way with the use of the Event Loop. Ryan Dahl, a talented developer, used Google Chrome's v8 JavaScript Engine and integrated it with a C++ application called Node to make this happen. The main goal of NodeJS was to enable server-side Javascript execution in addition to client-side execution. In contrast, servers have the ability to interface directly with the computer and its resources, enabling them to read files or keep data in databases. This indicates that JavaScript is not a type of programming language that can directly communicate with or control a computer or its resources.

Your browser offers a Runtime Environment that JavaScript needs in order to communicate with it (document, window, etc.). The JavaScript Engine of the browser runs JavaScript when a webpage is loaded and transforms it into computer-readable code. It is a straightforward and contemporary language. JavaScript was first developed to offer dynamic functionality to web pages inside the browser. This blog will describe how the dynamic NodeJS environment enables you to effectively scrape the web to satisfy the majority of your requirements. The necessary tools are now available for JavaScript, whether it's for a web or mobile application. Due to the significant advancements and the advent of the NodeJS runtime, JavaScript has emerged as one of the most well-known and often used languages.
