Examples of Relational Operators in JavaScript (AP CSP)

📚 Quick Study Guide

• 🔢 Relational operators are used to compare two values.
• ✅ They return a boolean value: `true` or `false`.
• ⚖️ Common relational operators include:
• == (equal to)
• != (not equal to)
• > (greater than)
• < (less than)
• >= (greater than or equal to)
• <= (less than or equal to)
• 💡 Example: 5 > 3 returns true.
• 💻 These operators are fundamental for conditional statements (if, else if, else) and loops.
