代码审查是软件开发生命周期的重要组成部分,但它们经常被误解或执行不力。让我们探讨一下它们为何重要以及如何有效地实现它们。
// Bad: Magic numbers function calculateDiscount(price) { return price * 0.85; } // Good: Clear intent const DISCOUNT_PERCENTAGE = 0.15; function calculateDiscount(price) { return price * (1 - DISCOUNT_PERCENTAGE); }
# Bad: SQL Injection vulnerability def get_user(username): query = f"SELECT * FROM users WHERE username = '{username}'" return db.execute(query) # Good: Parameterized query def get_user(username): query = "SELECT * FROM users WHERE username = ?" return db.execute(query, [username])
// Bad: O(n²) complexity function findDuplicates(array) { const duplicates = []; for (let i = 0; i < array.length; i++) { for (let j = i + 1; j < array.length; j++) { if (array[i] === array[j]) { duplicates.push(array[i]); } } } return duplicates; } // Good: O(n) complexity function findDuplicates(array) { const seen = new Set(); const duplicates = new Set(); array.forEach(item => { if (seen.has(item)) duplicates.add(item); seen.add(item); }); return Array.from(duplicates); }
