freeCodeCamp Challenge Guide: Comparison with the Inequality Operator

#1

The inequality operator (`!=`) is the opposite of the equality operator. It means “Not Equal” and returns `false` where equality would return `true` and vice versa. Like the equality operator, the inequality operator will convert data types of values while comparing.

## Examples

``````1 != 2      // true
1 != "1"    // false
1 != '1'    // false
1 != true   // false
0 != false  // false
``````

// Setup
function testNotEqual(val) {
if (val != 99) { // Change this line
return “Not Equal”;
}
return “Equal”;
}

// Change this value to test
testNotEqual(10);

help me … why my code is don’t work ?

function testNotEqual(val) {
if (val != 99) { // Change this line
return “Equal”;
}else if(val != ‘99’){
return ‘Equal’;
}else if(val != 12){
return “Not Equal”;
}else if(val != “12”){
return “Not Equal”;
}else if(val !=‘bob’){
return “Not Equal”;
}

}

// Change this value to test
testNotEqual(10);
