Names should be semantically meaningful and consistent across related concepts in the codebase. This applies to variables, functions, components, and types. When naming: 1. Use consistent suffixes/prefixes for related concepts 2. Choose descriptive verbs for functions 3. Avoid abbreviations unless widely understood 4. Maintain naming patterns across similar features Example of poor naming consistency: ```typescript // Inconsistent naming pattern interface User { customer_id: string; // Uses _id suffix group: string; // Missing _id suffix } function enableStreaminOption() {} // Misspelled, unclear verb ``` Improved version: ```typescript // Consistent naming pattern interface User { customerId: string; // Consistent camelCase groupId: string; // Consistent naming pattern } function createStreamingOption() {} // Clear verb, correct spelling ``` This helps maintain code readability and reduces cognitive load when working across different parts of the codebase.
