![]() The ecosystem is different and the goals are different, but the programming is the same JavaScript. Of course, creating Node applications and writing client scripts are completely different things. At the same time, Node.js provides full access to computer files and system functions through its own modules. We always operate in an isolated environment. In the browser, we mostly manipulate the DOM and work with the provided API. Node.js Support for Server-side Programming With the additional features of the integrated debugger, you will be able to promptly find bugs, inspect any scripts and debug JavaScript for both the front-end and back-end, using a single IDE interface. ![]() Also, it highlights lines with errors in the editor. To complete the debugging process, press Shift + F5, you can also delete the breakpoints by performing a mouse click again.ĬodeLobster constantly makes sure that your code is correct in terms of syntax. Adding to the list is done using the context menu, click on the variable name, and select “Add Watch”. Watch – the so-called “watch list”, here you can put your preferred variables, the values of which you want to control.Locals – it allows you to instantly evaluate the state of all variables available in the current script execution context. ![]() Call Stack – here you can view the call stack and trace the sequence of function calls.The application will be opened in the default browser window and script execution will be suspended on the first breakpoint. You can put one or more breakpoints by clicking the mouse to the left of the column with line numbers in the editor.Īfter that, press the F5 key to start the process or click on the “Live view” tab at the bottom of the program window. To start, set a breakpoint, this is the place in the script from which you want to start debugging. The built-in debugger allows you to pause the program at any stage of execution and assess the state of variables and the environment. If you are developing a complex application, you need much more control over the script execution process. The disadvantage is the fact that you get the data after the program has already completed its work. This is the easiest and fastest approach, it is suitable for checking small scripts. Inspecting Scripts with the Built-in DebuggerĮven novice programmers know the universal way to debug JavaScript using the function console.log(). Use requestAnimationFrame(), so you will get excellent performance in all types of modern browsers. Note that you no longer need the setInterval() or setTimeout() functions to play the animation. You can also instantly get a tooltip for any function, HTML element, or CSS property, just hover the mouse pointer over it. To enter the code quicker, use the hotkeys, press Ctrl + Space, and select the desired function from the list. Next, you will learn how to create and debug a script in the programming environment. In this case, we made a simple HTML page with a moving object. Support for Client-side JavaScript for Browsersįlash is a thing of the past and the new HTML5 capabilities combined with CSS and JavaScript allow you to perform any task without having to write a huge amount of code.įor example, CSS properties “animation” and “transition” are the first choice for creating effects on the site, but if we need a complex animation, we will certainly use JavaScript. This language is necessary for every progressive developer, let’s look at how CodeLobster copes with JS, Node, and modern frameworks. This article is about CodeLobster IDE – a fast universal programming environment for WEB with good JavaScript support. If you decide to make an interactive site with a functional UI, you will have to create software logic for your front end anyway. JavaScript is the only programming language that is fully supported by browsers without the use of additional extensions. The practice of JavaScript Programming with CodeLobster IDE
