![]() But generally, you should be able to bring up the developer tools by right clicking and selecting Inspect or Inspect Element, and then navigate to the Console tab from there. The steps to opening the console may be slightly different depending on the browser you use as well as your computer’s operating system. In this article, we’ll walk through how to open the developer console and run JS code right in your browser! Opening the browser console The console itself is also the place to view the messages that were logged by JS code, as well as any other information that the browser had documented, including network requests and security errors. The console is essentially a REPL ( Read-Evaluate-Print-Loop) that allows us to execute JS within the context of the page, such as modifying the page’s DOM ( Document Object Model) or logging to the console. JS code is normally added using the HTML element for executing in web browsers, but most modern browsers also provide a console as part of their developer tools where we can directly write and run JS, typically for testing and debugging purposes. Automated auditing, performance metrics, and best practices for the web.Along with HTML and CSS, JavaScript (JS) makes up one of the core languages in web development. Type inference and checking for a safer JavaScript. Run JavaScript and TypeScript in node.js within VS Code notebooks with excellent support for debugging, tensorflowjs visulizations, plotly, danfojs, etc A utility-first CSS framework for rapid UI development. why-did-you-render by Welldone Software monkey patches React to notify you about potentially avoidable re-renders. Python extension for Visual Studio Code Glamorous Toolkit is a multilanguage notebook. A sandboxed JavaScript interpreter in JavaScript. When comparing quokka and RunJS you can also consider the following projects: how do you debug your view application?.Without you having to go to an external context like a debug window to see the bindings. Effectively animating the flow of data through your code. In fact, since a program is about binding values to the symbols in your code, when running your code, the IDE, enabled by the content-addressable code feature), could replace variables in the text with their bound values, successively. The REPL-driven development approach should ideally afford simply changing code in the code editor, detecting the change, and showing the result then and there, without you having to go to back-and-forth to a separate REPL-shell and copy-pasting / retyping code. ![]() ![]() But with the ability to see the content of the data structures within your IDE. Especially good for debugging: getting the exact program state from loading up an image of it that someone sent you. Some have described this as REPL-driven-development, or interactive-programming. But without being a whole isolated universe in its own right like a VM or an isolated image. So the language should make such visualization and code-augmentation easy for tooling to support. It shouldn't be necessary for the programmer to take the effort to visualize it in his mind (with the error-proneness that entails). Since "An algorithm has to be seen to be believed", as D.E. Also, it should be possible to visualise/animate an algorithm. Ideally with example data, not only the data type. Structure he/she is working on, at any given time, in the code. Programmer should always be able to see the data No need to manipulate data structures in the human mind.
