56533eb9ac21ba0edf2244d1	Comparison with the Strict Equality Operator	1	https://scrimba.com/c/cy87atr	16790

Description

Strict equality (===) is the counterpart to the equality operator (==). However, unlike the equality operator, which attempts to convert both values being compared to a common type, the strict equality operator does not perform a type conversion. If the values being compared have different types, they are considered unequal, and the strict equality operator will return false. Examples

3 ===  3   // true
3 === '3'  // false

In the second example, 3 is a Number type and '3' is a String type.

Instructions

Use the strict equality operator in the if statement so the function will return "Equal" when val is strictly equal to 7

Tests

tests:
  - text: <code>testStrict(10)</code> should return "Not Equal"
    testString: assert(testStrict(10) === "Not Equal");
  - text: <code>testStrict(7)</code> should return "Equal"
    testString: assert(testStrict(7) === "Equal");
  - text: <code>testStrict("7")</code> should return "Not Equal"
    testString: assert(testStrict("7") === "Not Equal");
  - text: You should use the <code>===</code> operator
    testString: assert(code.match(/(val\s*===\s*\d+)|(\d+\s*===\s*val)/g).length > 0);

Challenge Seed

// Setup
function testStrict(val) {
  if (val) { // Change this line
    return "Equal";
  }
  return "Not Equal";
}

testStrict(10);

Solution

function testStrict(val) {
  if (val === 7) {
    return "Equal";
  }
  return "Not Equal";
}
