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

function checkEqual(a, b) {

checkEqual(1, 2);
--solutions--
function checkEqual(a, b) {
return a === b ? "Equal" : "Not Equal";
