Multiple choice questions on Comparison Operators in JavaScript for Grade 7

📚 Quick Study Guide

• 🔢 What are Comparison Operators? These operators compare two values and return a boolean result (true or false).
• ✅ Equal to (==): Checks if two values are equal, but it doesn't check the data type. For example, 5 == "5" is true.
• 💯 Strict Equal to (===): Checks if two values are equal AND of the same data type. For example, 5 === "5" is false because one is a number and the other is a string.
• ✔️ Not Equal to (!=): Checks if two values are not equal. Like ==, it doesn't check the data type.
• 🚫 Strict Not Equal to (!==): Checks if two values are not equal OR are not of the same data type.
• 📈 Greater Than (>): Checks if the left value is greater than the right value. For example, 10 > 5 is true.
• 📉 Less Than (<): Checks if the left value is less than the right value. For example, 5 < 10 is true.
• 📚 Greater Than or Equal To (>=): Checks if the left value is greater than or equal to the right value. For example, 10 >= 10 is true.
• 🔢 Less Than or Equal To (<=): Checks if the left value is less than or equal to the right value. For example, 5 <= 10 is true.
