Enabling Java Script In Ie – You can debug JavaScript and TypeScript code using Visual Studio. You can hit breakpoints, attach a debugger, examine variables, view the call stack, and use other debugging features.

If you haven’t installed Visual Studio yet, go to the Visual Studio download page and install it for free. Depending on the type of application development you are doing, you may need to install a Node.js development workload using Visual Studio.

Visual Studio only provides client-side debugging support for Chrome and Microsoft Edge (Chromium). In some cases, the debugger automatically hits breakpoints in embedded scripts in JavaScript and TypeScript code and HTML files. For more information on debugging client-side scripting in ASP.NET applications, see the Debug JavaScript in Microsoft Edge blog post and this Google Chrome post. For more information about debugging TypeScript in ASP.NET Core, see Creating an ASP.NET Core application with TypeScript.

Using Your Browser To Diagnose Javascript Errors

If your source is minified or generated by a converter such as TypeScript or Babel, use resource maps for the best debugging experience. You can also attach the debugger to a running client-side script without resource maps. However, you can only set and reach breakpoints in the minified or migrated file, not in the source file. For example, in a Vue.js application, the minified script is passed as the string an

Expression, and this code cannot be effectively passed to the Visual Studio debugger unless you use resource maps. Use Chrome Developer Tools or F12 Tools for Microsoft Edge for complex debugging situations.

Attaching the debugger from Visual Studio and hitting breakpoints in client-side code needs help determining the correct process. Here’s a way to enable it.

If you need to enter code in a TypeScript or JSX source file and can’t, attach the debugger using Attach to Process as described in the previous section. Make sure your environment is configured correctly:

Expression in the source file or set breakpoints instead in Chrome Developer Tools (or F12 Tools for Microsoft Edge).

Visual Studio has the ability to access and create resource maps in JavaScript source files. This is often necessary if your source is minified or generated using a converter such as TypeScript or Babel. The available options depend on the type of project.

To enable debugging with Visual Studio, you need to ensure that the source file references in the generated source map are correct (this may require testing). For example, if you’re using webpack, include references to the sourcemap file

There are several tools and techniques available for testing JavaScript in the browser that can be used. Each tool has a set of unique features that contribute to different results. While it can be difficult to narrow down to one tool that meets all of your testing needs in this regard, consider using a combination of tools to achieve your desired business and product goals.

The purpose of this article is to describe 5 ways to instantly test JavaScript code in commonly used browsers. So let’s start with the first tool.

While JavaScript can be instantly tested using tools such as CodePen and JSFiddle, there is no way to check the behavior of these scripts across different desktop and mobile browsers. This is where online cross-browser testing platforms come into play.

Developers and QA can check their website for cross-browser compatibility using tools such as . With this platform, a developer or QA can instantly test their websites on many real mobile devices and browsers like Chrome, Safari, IE, Edge, Firefox, etc.

Users can also use features like responsive layout testing and screenshot testing to help test the validity of JavaScript on a particular web page. See this list of browsers and mobile devices that provided JavaScript for testing.

The wide range of OS browser combinations as well as the latest real devices for testing purposes is unmatched. Using and testing Javascript is relatively easy in any browser of your choice.

JSFiddle is an online tool that allows QA to test HTML, CSS and JavaScript code right in the browser. It was introduced in 2009 and was originally known as Mooshell. This tool is compatible with popular JavaScript frameworks like Vue, React, etc. Here HTML, CSS and JavaScript snippets are called violins. JSFiddle is known for its easy-to-use interface.

The user can write JavaScript as well as HTML and CSS and review the results in place. JSFiddle’s dashboard is quite upfront and is divided into three parts – HTML, CSS and JavaScript. See the image below for better understanding.

Introduced in 2012, CodePen is a JSFiddle-like web platform for testing snippets of HTML, CSS and JavaScript code, also called pens. One can start writing a script in the editor and immediately test the code to get the desired results. However, CodePen is not just limited to coding and testing; it acts as a social community that provides an online learning environment. Aspiring developers can share their work on this platform.

With a whopping 33,000 active users, it’s one of the largest developer communities on the web. CodePen offers many interesting features like Asset hosting collaboration mode and many more.

Asset hosting allows the user to directly drag and drop images without worrying about separate hosting. Hosting of other assets such as CSS and JSON files is taken care of.

JSBin is a powerful alternative to JSFiddle. Its features also allow users to experiment, learn and teach. A script written by a particular user and stored in JSBin is called a container.

You can easily start testing containers written in HTML, CSS and JavaScript using the built-in editor. You can also access premium features like private trash, Dropbox backup by upgrading to the pro version. See the image below for a clear view of the JSBin interface.

Note: Once JavaScript code changes are made, they must be tested on multiple real browsers and devices to ensure compatibility with each device-browser combination. Test JavaScript on over 3000 real browsers and devices in a real device cloud. Free to try.

Liveweave is another coding platform that allows developers or web designers to write, test, and share JavaScript, HTML, and CSS code with their team. This platform offers some interesting features like live preview, night mode and code hints. In particular, code hinting makes programming easier for beginners by providing a drop-down list of commonly used identifiers. Liveweave also supports some popular libraries like jQuery, AngularJS and Bootstrap.

These simple ways to test JavaScript can be very useful for developers and web designers. However, users may also choose to use developer tools for certain browsers. For example, QA can fix JavaScript errors by using the JavaScript console in Chrome’s developer tools. Also, DevTools for other popular browsers such as Firefox, Safari can be used as a powerful alternative to the tools described above.

When it comes to testing a website in multiple browsers, using Devtools in individual browsers can be time consuming. A smart approach might be to use general-purpose tools in the early stages of testing and use browser-specific Devtools to handle browser-specific test cases.

Running tests using a tool like this helps a QA engineer leverage their test script execution as it covers a wider aspect of testing in terms of platforms, browsers and device coverage. As a result, tools like Codepen and JSFiddle have an edge over others.
