Tell us what’s happening:

Your code so far


var myVar = 87;

// Only change code below this line
myVar = 87 + 1;
++87;

I can’t seem to be getting how to use ++ to make number to be 88


#3

Try this and see if you can understand what is happening. Then change the myVar accordingly.

var i = 0;
console.log("this is the iniliasation of the value i: " + i);
i++;
console.log("this is the endvalue of i : "+ i);

An extra tip. You need to change the exact line of myVar = 87 + 1;


#4

If you’re trying to get a counter to increment myVar at every run:

var myVar = 87;
function updatevar(){
return console.log( myVar++);
}
updatevar(); // 87
updatevar(); // 88
updatevar(); // 89


#5

Just replace myVar = myVar + 1; with myVar++;
Because myVar = myVar + 1; is same as myVar++;
