Problem / steps to reproduce (for bugs)

• Many functions in the project currently lack proper comments or documentation.
• This makes it difficult for other developers to understand, maintain, or contribute to the codebase.
• There is no consistent pattern for function documentation across the project.

Expected outcome / task:

• Go through the entire codebase and add clear function-level documentation for all functions.
• Each function documentation should include:
  • Function name
  • Purpose / description of what the function does
  • Parameters: names, types, and description
  • Return value: type and description
  • Any side effects if applicable
• Use standard commenting patterns, e.g. JSDoc for JavaScript / TypeScript: `ts /**
  • Calculates the sum of two numbers.
  • @param {number} a - The first number
  • @param {number} b - The second number
  • @returns {number} The sum of a and b */ function sum(a: number, b: number): number { return a + b; }
