If you are looking at the results in the console, perhaps what you see is the console telling you it combined the two duplicate messages — JonSG, Jul 31 '18 at 21:42

What you're seeing in your console is an output of occurrences for each of the console.logs so the 2l is really just saying there are two occurrences of l being logged.

Example Console Output

Here's your code again, but this time with the code being added to an array, then the array being printed.

var str = "ahceclwlxo";
var result = []
for (var i = 1; i <str.length; i+=2){
  result.push(str[i])
}
console.log(result)

That prints out (5) ["h", "e", "l", "l", "o"] in chrome's console. Indicating that you have an array with a length of 5.

Why the downvote? This is *exactly* an explanation of the issue! – JonSG Jul 31 '18 at 21:44
@JonSG Likely because it seems this is the second time they've asked nearly the same question. This should really have been closed as a duplicate of the first. – Carcigenicate Jul 31 '18 at 21:47
@Carcigenicate Ahh, I see. – JonSG Jul 31 '18 at 21:49

Some browsers' console windows are configured to not actually reprint similar outputs repeatedly. Instead they print out the first copy and display the number of repetitions.
