TypeScript/JavaScript JSDoc
typescript
/**
* Calculates the total price including tax.
*
* @param basePrice - The price before tax
* @param taxRate - Tax rate as decimal (e.g., 0.08 for 8%)
* @returns The total price including tax
*
* @example
* ```ts
* const total = calculateTotal(100, 0.08);
* console.log(total); // 108
* ```
*/
function calculateTotal(basePrice: number, taxRate: number): number {
return basePrice * (1 + taxRate);
}
Examples
User asks: "Help me write documentation for my API"
Response approach:
- •Ask about the API's purpose and target audience
- •Identify all endpoints and their methods
- •Document request/response formats with examples
- •Include authentication requirements
- •Add error codes and troubleshooting
- •Provide quickstart guide for common operations
