Why These Guides?

As developers, we use tools like JSON formatters, Base64 encoders, and hash generators daily. But understanding the why behind these tools makes you a better developer. These guides explain the fundamentals so you can make informed decisions and avoid common pitfalls.

Practical Focus
Every guide includes real-world examples, code snippets, and scenarios from actual development work. No theoretical fluff—just practical knowledge you can apply immediately.
Best Practices
Learn the recommended approaches, common mistakes to avoid, and security considerations. Each guide includes checklists and decision matrices for quick reference.
Tool Integration
Each guide links to relevant tools on CodingTool.dev so you can immediately practice what you've learned. See the concepts in action with our interactive utilities.
Up-to-Date
Guides reflect current best practices as of 2024, including modern browser APIs, security standards (OWASP recommendations), and framework conventions (Node.js, React, Next.js).

More Guides Coming Soon

We're continuously adding new guides based on developer feedback and common questions. Topics in the pipeline include:

  • • Regular Expressions for Developers (regex patterns, testing, common use cases)
  • • JWT Tokens Explained (structure, validation, security best practices)
  • • API Design: REST vs GraphQL (when to use each, versioning strategies)
