--description--
The conditional operator, also called the ternary operator, can be used as a one line if-else expression.
The syntax is:
condition ? expression-if-true : expression-if-false;
The following function uses an if-else statement to check a condition:
function findGreater(a, b) {
if(a > b) {
return "a is greater";
}
else {
return "b is greater";
}
}
This can be re-written using the conditional operator
:
function findGreater(a, b) {
return a > b ? "a is greater" : "b is greater";
}
--instructions--
Use the conditional operator
in the checkEqual
function to check if two numbers are equal or not. The function should return either "Equal" or "Not Equal".
--hints--
checkEqual
should use the conditional operator
assert(/.+?\s*?\?\s*?.+?\s*?:\s*?.+?/.test(code));
checkEqual(1, 2)
should return "Not Equal"
assert(checkEqual(1, 2) === 'Not Equal');
checkEqual(1, 1)
should return "Equal"
assert(checkEqual(1, 1) === 'Equal');
checkEqual(1, -1)
should return "Not Equal"
assert(checkEqual(1, -1) === 'Not Equal');
--seed--
--seed-contents--
function checkEqual(a, b) {
}
checkEqual(1, 2);
--solutions--
function checkEqual(a, b) {
return a === b ? "Equal" : "Not Equal";
}
