1 Use a code editor

A code editor is a software that helps you write and edit code with features such as syntax highlighting, auto-completion, indentation, and formatting. A good code editor can also help you find and fix errors by pointing out syntax errors, spelling mistakes, and code quality issues. Some of the popular code editors for web development are Visual Studio Code, Sublime Text, and Atom. You can also use extensions and plugins to enhance your code editor with additional functionalities and integrations.

Almost all developers use specific language debuggers to track and fix the errors. Regarding the quality of the code, we can use code editor plugins, browser tools, and specific language style guides. Eg. PEP8 for Python. But what if we can avoid these errors in the first place rather than fixing the same issues at multiple places? Simple using programming principles. DRY, SOLID, KISS, etc..

Lately, code editors have tons of AI extensions/plugins to help you while you write your code. This leads to fewer bugs and more optimal code as suggested by the AI plugin while you are typing your code. Also, it helps you to keep your code clean and simple so the other team members won't have a hard time figuring your code out and it will help you have less technical debt.

2 Use browser tools

Browser tools are built-in or add-on tools that let you inspect and manipulate the elements, styles, scripts, and network activity of your web project in the browser. They can help you find and fix errors by allowing you to debug your code, test different scenarios, and monitor performance. Some of the common browser tools for web development are Chrome DevTools, Firefox Developer Tools, and Safari Web Inspector. You can also use browser extensions to add more features and tools to your browser.

3 Use a debugger

A debugger is a tool that helps you find and fix errors in your code by letting you pause, step through, and examine the execution of your code. A debugger can help you identify the root cause of an error, check the values of variables and expressions, and modify the code on the fly. Some of the debugger tools for web development are Visual Studio Code Debugger, Chrome DevTools Debugger, and Node.js Debugger. You can also use breakpoints, watch expressions, and console commands to control and manipulate your code with a debugger.

4 Use a linter

A linter is a tool that analyzes your code for potential errors, bugs, and style issues. A linter can help you find and fix errors by enforcing consistent coding standards, highlighting syntax errors, and suggesting best practices. Some of the linter tools for web development are ESLint, Stylelint, and Prettier. You can also use configuration files and rules to customize your linter according to your preferences and project requirements.

Linter will help you with keeping your code clean and readable. Some linters are very primitive and will only reformat your code. Others are a bit smarter and can recognize some code patterns and offer to reformat your code to make it more readable, which Is a good reason not to skip the code listing step.

5 Use a testing tool

A testing tool is a tool that helps you verify the functionality, performance, and usability of your web project by running automated or manual tests. A testing tool can help you find and fix errors by detecting bugs, regressions, and failures before they affect your users. Some of the testing tools for web development are Jest, Mocha, and Cypress. You can also use frameworks, libraries, and methodologies to structure and organize your tests.

Testing is a CRUCIAL part of every software. Whether it is a QA that will manually check your application or write automation tests, or the developer writing good unit and integration tests. As the application grows, more and more features come along and while adding them you may break something else. That's why tests are there - to ensure that everything works as before and that your new feature works on top of the old features.

6 Use a logging tool

A logging tool is a tool that helps you collect, store, and analyze the data generated by your web project during runtime. A logging tool can help you find and fix errors by providing you with detailed information about the events, errors, and exceptions that occur in your web project. Some of the logging tools for web development are Winston, Bunyan, and Loggly. You can also use dashboards, alerts, and reports to monitor and troubleshoot your web project with a logging tool.
