My solution:

function passandoPelosPares() {
for (var i=0; i <=6; i++)
  console.log ('aqui eu tenho o valor de' + i)
}

Reply 'insufficient':

Print out passandoPelosPares() must print:

aqui eu tenho o valor de 0
aqui eu tenho o valor de 2
aqui eu tenho o valor de 4
aqui eu tenho o valor de 6

What I’m doing wrong?

Probably missing a space in the printing, the automatic broker of the site wants something exact, can not miss even the space. But I took advantage and simplified and gave more performance to the code apart from the if, it doesn’t make sense to have that code you can do without it.

function passandoPelosPares() {
    for (var i = 0; i <= 6; i+= 2) console.log('aqui eu tenho o valor de ' + i);
}
passandoPelosPares();

I put in the Github for future reference.

I put the function call just to run here, there on this site it should call on its own and do not need this line.

  • Thank you, I remade the solution and it worked!

In your code in the loop for you’re always adding more 1 in the variable i every iteration of the loop for which will not give you the result in 2 and 2 and yes in 1 in 1, then change from i ++ for i += 2, add a space at the end of the String not to be together with the text and the number and just call the function passandoPelosPares();.

Example 1

function passandoPelosPares() {
for (var i = 0; i <= 6; i += 2)
  console.log ('aqui eu tenho o valor de ' + i)
}

passandoPelosPares();

In case you want a sequence in 2, 4, 6 and not 0, 2, 4, 6 just start the variable i with 2 and not with 0.

Example 2

function passandoPelosPares() {
for (var i = 2; i <= 6; i += 2)
  console.log ('aqui eu tenho o valor de ' + i)
}

passandoPelosPares();

I executed your code and the result was:

aqui eu tenho o valor de0
aqui eu tenho o valor de2
aqui eu tenho o valor de4
aqui eu tenho o valor de6

Which leads me to believe that the problem is the gap between "de" and "par".

In this case, simply replace the "+" with "," in your console.log.

You don’t need the if if the step of your for for every 2, changing i++ for i+=2.

Also, it may be lacking to perform the function, and you can do this involving the function with () and putting the parentheses at the end, this way:

(function passandoPelosPares() { 
    for (var i=0; i <=6; i+=2) 
        console.log ('aqui eu tenho o valor de', i) 
})()

  • But none of the solutions worked.
