CODE DOCUMENTATION ~ Assisting AI

 “Readability documentation of source code for future code modification” refers to writing and organizing code in a way that makes it easy for other developers — or your future self — to understand, maintain, and modify later.

Key aspects usually include:

Clear variable and function names

Consistent formatting and indentation

Comments explaining complex logic

Documentation blocks (docstrings, JSDoc, etc.)

Modular structure

Version/change notes

Separation between logic and presentation

Readable flow and architecture

Example:

Bad readability:

function x(a,b){return a*b*0.1}

Better readability:

/**

 * Calculate 10% tax from product price.

 * @param {number} price

 * @param {number} quantity

 * @returns {number}

 */

function calculateTax(price, quantity) {

    const subtotal = price * quantity;

    const taxRate = 0.1;

    return subtotal * taxRate;

}

Benefits for future modification:

Easier debugging

Faster onboarding for new developers

Lower risk when adding features

Reduced maintenance cost

Better collaboration

Easier scalability
