Quick Questions
Shade in the A or B circle for each question.
1. Does === check if two values are equal in both value and type?
2. Does !== check if two values are not strictly equal?
3. Is = a valid way to check if two values are equal?
4. Does > check if the left value is greater than the right?
5. Does < check if the left value is smaller than the right?
B
Match the Pairs
Draw a line connecting each item on the left to its match on the right.
| Left column | Right column | |
|---|---|---|
| 15 === 5 | AReturns true because both values and types match | |
| 25 !== 3 | BWrong - the strict inequality operator is !==, not !=== | |
| 3Compares if one value is greater than another | CReturns true because the values are not equal | |
| 4Compares if one value is less than another | DWrong - use === for comparison, = is for assignment | |

Answer Key
Comparison Operators
Section A: Quick Questions
Q1
A — Yes
Q2
B — Yes
Q3
A — No
Q4
A — Yes
Q5
B — Yes
Section B: Match the Pairs
Q1
5 === 5 → Returns true because both values and types match
Q2
5 !== 3 → Returns true because the values are not equal
Q3
Compares if one value is greater than another → 10 > 7
Q4
Compares if one value is less than another → 3 < 8
Q5
console.log(5 = 5); → Wrong - use === for comparison, = is for assignment
Q6
console.log(5 !=== 3); → Wrong - the strict inequality operator is !==, not !===
Section C: Definitions
Q1
=== — Checks if two values are equal in both value and type, returning true or false.Section D: Fill in the Blanks
Q1
console.log(5 === 5);Q2
console.log(5 !== 3);Q3
console.log(10 > 7);Q4
console.log(3 < 8);Q5
let isEqual = age === 12;Section E: Spot the Error
Q1
A — Use === for comparison, not =, which is for assignment.
Q2
B — The strict inequality operator is !==, not !===.
Q3
A — Use <= not =<, to check less than or equal.
Q4
B — => is not a comparison operator - use >= for this check.
Q5
C — This module uses ===, not the loose ==, for equality checks.
