* This function aims to demonstrate how one can effectively document JavaScript code.
* It features a simple calculator that performs basic arithmetic operations: addition,
* subtraction, multiplication, and division. Each function is thoroughly documented to
* illustrate best practices in JavaScript documentation.
*/
/**
* Adds two numbers.
* @param {number} num1 The first number to add.
* @param {number} num2 The second number to add.
* @returns {number} The sum of num1 and num2.
*/
function add(num1, num2) {
return num1 + num2;
}
/**
* Subtracts one number from another.
* @param {number} num1 The number to subtract from.
* @param {number} num2 The number to subtract.
* @returns {number} The difference between num1 and num2.
*/
function subtract(num1, num2) {
return num1 - num2;
}
/**
* Multiplies two numbers.
* @param {number} num1 The first number to multiply.
* @param {number} num2 The second number to multiply.
* @returns {number} The product of num1 and num2.
*/
function multiply(num1, num2) {
return num1 * num2;
}
/**
* Divides one number by another.
* @param {number} num1 The dividend.
* @param {number} num2 The divisor.
* @returns {number} The quotient of num1 divided by num2.
* @throws {Error} Throws an error if num2 is 0, as division by zero is not allowed.
*/
function divide(num1, num2) {
if (num2 === 0) {
throw new Error('Division by zero is not allowed.');
}
return num1 / num2;
}
// Example usage
const sum = add(5, 3);
const difference = subtract(10, 5);
const product = multiply(4, 2);
let quotient;
try {
quotient = divide(20, 0);
} catch (error) {
console.error(error.message);
}
### Code Output:
Division by zero is not allowed.
### Code Explanation:
This program showcases a simple calculator that performs addition, subtraction, multiplication, and division, wrapped with comprehensive JavaScript documentation to serve as a guide. Here’s a rundown of its architecture and logic:
- Introduction and Purpose: The initial comments clarify the purpose of this snippet, highlighting its role as an illustrative tool for effective JavaScript documentation.
- Functions and Parameters: Each arithmetic operation—
add,subtract,multiply, anddivide—is encapsulated within its own function. These functions are thoroughly documented, specifying their expected parameters (num1andnum2), both marked with{number}to denote their type, and detailing the return value, also a{number}, which represents the result of the arithmetic operation. - Error Handling in Documentation: The
dividefunction documentation goes a bit further by detailing potential error handling, specifically noting that anErrorwill be thrown if attempting to divide by zero, demonstrating how to document potential exceptions and special cases. - Execution and Example Usage: Following the function definitions, the script performs a series of operations—addition, subtraction, multiplication, and an attempted division by zero, which causes an error to be thrown and caught. This part not only serves as a practical example of using the documented functions but also emphasizes the importance of error handling in real-world applications.
- Error Handling: The try-catch block around the
dividefunction call showcases practical error handling, catching and logging a division-by-zero error, aligning with the documented behavior of thedividefunction.
By meticulously documenting each function and including examples of error handling, the script not only performs simple arithmetic operations but also serves as a comprehensive guide to JavaScript documentation practices, stressing clarity, detail, and anticipation of potential errors or exceptional cases.
