Increment a Number with JavaScript by Daniel

Increment a Number with JavaScript by Daniel


I am trying to change the code ++ to get the value of 88 but I’m lost. Please help me.

Your code so far

var myVar = 87;

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

How did you try to use the ++ arithmetic operator?
Did you read the material suggested by the instructions (and looked at the examples?


Yes I did but still no results…


Also in the instructions says that:

is the equivalent of
i = i + 1;

Try to do the same with the exercise.
In the example i is the variable that is increased. In the exercise the variable is myVar.


See what I did. Yet no result.

var myVar = 87;

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


By doing that you are incrementing myVar twice, becoming 89. To pass this exercise only use the line with myVar++.


I’m sorry but I don’t understand your explanation.


The initial value of myVar is 87:
var myVar = 87;

Then , these two lines of code, are interpreted/executed one after the other

myVar = myVar + 1;


The first one makes myVar to be 88, and the next 89.

The instructions asks for only adding one to myVar, and to use the ++ arithmetic operator, so you only need to use myVar++;


The question says:

Change the code to use the ++ operator on myVar.

Learn more about Arithmetic operators - Increment (++).


That is what I am trying to say in other words.
Also, the expected result for myVar is to be 88:
If you look at the test messages below the green buttons:

myVar should equal 88

You almost write the right code, the only problem is that you left the myVar = myVar + 1; unchanged. You need to replace that line with the code that uses the equivalent myVar++;


Thanks so much. It’s Done.
