A JavaScript engine and a render engine are both important components of a web browser. However, they have different functions. This guide explores browser engines, their implementations, and specialized Firefox-based alternatives that offer enhanced privacy, performance, and customization options.

JavaScript Engine​

A JavaScript engine is responsible for executing JavaScript code. JavaScript is a programming language that is used to add interactivity to web pages. When a web page contains JavaScript code, the browser's JavaScript engine is responsible for parsing and executing JS code. It uses JIT compilation for improved performance.

Render Engine​

A render(rendering) engine is responsible for displaying the content of a web page on the screen. This includes the HTML, CSS, and JavaScript code. The render engine takes the code and converts it into a visual representation that can be displayed on the screen. In browsers, it works in conjunction with the JavaScript engine via the DOM(Document Object Model). A rendering engine is also known as a browser engine or layout engine. A browser engine is a core software component of every major web browser.
