Detailed introduction to 7 debugging tools to improve efficiencyJavaScript

Now JavaScript has actually become a popular web language, even if it is not perfect . Many programmers don’t like to write code in JavaScript because all kinds of inexplicable bugs will always appear after writing, and it is easy to make mistakes in the process of developing large applications. And given the current state of such tools today, it's not that convenient to do JavaScript debugging on the browser.

The following desktop and WEB-based JavaScript debugging tools allow you to debug JavaScript code more efficiently, so you can:

  • Handle dynamic types more efficiently

  • Make applications more compliant with coding standards

Firebug

Firebug has been around for many years and provides an app extension for developers who primarily create apps on Firefox.

  • is a dedicated application for HTML, CSS and JavaScript testing

  • is more powerful than the developer tools that come with the default browser

  • Allows setting breakpoints to facilitate testing results at various stages

If you are on other browsers, such as Google Chrome If you are developing programs on the browser, you can try the streamlined version of Firebug. The functions are the same, but the interface is slightly different.

Opera Dragonfly

The Opera browser is not very popular and is used by less than 1% of the world's Internet users. However, its open JavaScript testing and debugging tools may appeal to you.

  • Inspect the DOM more easily

  • Immediately see the results of modifying CSS and JavaScript

  • Check errors and find their root cause faster

Other browsers are improving to rival Opera Dragonfly, but for now it's still the best for web developers One of the testing tools.

Debug bar

Internet Explorer does not provide as many plug-ins as Firefox and Chrome, but for this browser that is currently the most used in the world As far as browsers are concerned, DebugBar is one of the best front-end debugging tools. It covers almost all the features you need:

  • DOM Inspection

  • Cookie Inspection

  • JavaScript Debugging

If your primary browser is Internet Explorer, DebugBar is definitely a smart choice among advanced JavaScript tools.

JSLint

JSLint is developed by Douglas Crock, one of the most well-known technical authorities in the field of web development in the world todayfor## A web-based tool created by #d. All you need to do is copy and paste the code into JSLint’s online editor and you’ll:

  • Highlight errors in the code

  • Make sure the syntax is concise and standard

  • Point out common JavaScript type errors.

JSLitmus


If you care about the performance of your JavaScript applications, JSLitmus is definitely a cute little tool. It helps you create your own JavaScript benchmarks so you can weigh performance at various stages of app development.

Write Code Online


Writecodeonline.com is a full-featured JavaScript editor. It's simple to use and can pinpoint bugs almost immediately. It is an indispensable assistant for large-scale applications.

Tinkerbin

This is one of the best online web development and design tools currently available. Tinkerbin allows you to test HTML, CSS and JavaScript in the same web application. The reason why using Tinkerbin is more convenient for testing the impact of JavaScript code snippets on HTML and CSS is that you can see the immediate results.

We may find JavaScript cumbersome, but that’s because it will evolve gradually, rather than being some grand design from the beginning. The tools and applications above can benefit your development and testing. And there is always a browser that suits you, helping you develop apps more efficiently and without bugs.

From Websites to Apps: The Diverse Applications of JavaScriptFrom Websites to Apps: The Diverse Applications of JavaScriptApr 22, 2025 am 12:02 AM

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python vs. JavaScript: Use Cases and Applications ComparedPython vs. JavaScript: Use Cases and Applications ComparedApr 21, 2025 am 12:01 AM

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

The Role of C/C   in JavaScript Interpreters and CompilersThe Role of C/C in JavaScript Interpreters and CompilersApr 20, 2025 am 12:01 AM

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript in Action: Real-World Examples and ProjectsJavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AM

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

JavaScript and the Web: Core Functionality and Use CasesJavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsUnderstanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UsePython vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesPython vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.
