CamelCase vs. snake_case vs. kebab-case: The Developer Naming Guide

  <h2>Why Consistent Case Formatting Matters</h2>
  <p>Inconsistent casing in codebases creates silent bugs, breaking JSON deserialization, CSS selectors, and SQL column mappings. Different programming languages adhere to strict cultural casing standards.</p>

  <h3>Where Each Casing Style Belongs</h3>
  <ul>
    <li><strong>camelCase:</strong> Standard for JavaScript / TypeScript variables and function names (e.g. <code>getUserProfile</code>).</li>
    <li><strong>PascalCase:</strong> Reserved for React components, classes, and TypeScript interfaces (e.g. <code>UserProfileCard</code>).</li>
    <li><strong>snake_case:</strong> Standard for Python variables, database column names, and REST URL query keys (e.g. <code>user_profile_id</code>).</li>
    <li><strong>kebab-case:</strong> Universal for URL slugs, HTML custom attributes, and CSS class names (e.g. <code>user-profile-card</code>).</li>
  </ul>
