## Overview

The Variable Name Validator checks if your variable names adhere to the naming conventions of popular programming languages. Enter a name, select a language and style, and get instant validation feedback to ensure code quality and consistency.

## Inputs

- **Variable Name** (text): Enter variable name to validate...
- **Programming Language** (select)
- **Naming Style** (select)

## When to use

- When writing or reviewing code to ensure variable names follow language-specific standards.
- During onboarding or training to help new developers learn correct naming conventions.
- In automated workflows to enforce naming rules before code commits or deployments.

## How it works

- Enter the variable name you want to validate in the input field.
- Select the target programming language from the dropdown menu, such as JavaScript or Python.
- Choose a naming style like camelCase or snake_case, or use auto-detect to identify the convention.
- Receive a JSON result indicating if the name is valid, the detected style, and any mismatches.

## Use cases

- Developers ensuring code quality by adhering to team naming standards in projects.
- Educators teaching programming conventions to students with practical validation examples.
- CI/CD pipelines integrating the tool to automatically check variable names in code repositories.

## Frequently asked questions

### What programming languages are supported?

The tool supports JavaScript, Python, Java, C#, Go, Rust, PHP, and can check against all languages simultaneously.

### Can I validate multiple variable names at once?

No, the tool validates one variable name at a time for precise and focused checking.

### What naming styles are available?

You can choose from camelCase, PascalCase, snake_case, SCREAMING_SNAKE_CASE, kebab-case, or use auto-detect.

### Is the validation case-sensitive?

Yes, the tool checks for exact case matching as per the selected naming convention and language standards.

### What does the JSON result include?

The result indicates whether the name is valid, the detected or selected style, and details on any errors or suggestions for correction.
