| 56533eb9ac21ba0edf2244d1 | Comparison with the Strict Equality Operator | 1 | https://scrimba.com/c/cy87atr | 16790 | comparison-with-the-strict-equality-operator |
--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 the string Equal when val is strictly equal to 7.
--hints--
testStrict(10) should return the string Not Equal
assert(testStrict(10) === 'Not Equal');
testStrict(7) should return the string Equal
assert(testStrict(7) === 'Equal');
testStrict("7") should return the string Not Equal
assert(testStrict('7') === 'Not Equal');
You should use the === operator
assert(code.match(/(val\s*===\s*\d+)|(\d+\s*===\s*val)/g).length > 0);
--seed--
--seed-contents--
// Setup
function testStrict(val) {
if (val) { // Change this line
return "Equal";
}
return "Not Equal";
}
testStrict(10);
--solutions--
function testStrict(val) {
if (val === 7) {
return "Equal";
}
return "Not Equal";
}
