<Below this line, in what way does your code behave incorrectly? Include ALL error messages.>
Hi, i just finished this task by writing code below, it was accepted, but the output was strange:
I know someone called 1
I know someone called 2
I know someone called 3
I know someone called 4
I know someone called 5
I know someone called function (testArr) {
if (this.length !== testArr.length) return false;
for (var i = 0; i < testArr.length; i++) {
if (this[i].equal) {
if (!this[i].equal(testArr[i])) return false;
}
if (this[i] !== testArr[i]) return false;
}
return true;
}
Why did this happen?
```
var names = [“1”, “2”, “3”, “4”, “5”];
for (var name in names) {
console.log("I know someone called " + names[name]);
}
Did you just used the code below? Couldn’t reproduce it using the code on the exercise in the link.
Was there an error message or just this output?
PS: Also be careful to use “name” as a variable name because it is something like a keyword or at least has some features you would not expect it to have (e.g. it is always a string even if you assign a number or boolean).
I know how it should be using the names[i] syntax, I just wondered, what if I make it another way =)
I just cheched, and found something: if I just click “Save and Submit”, it works fine with no strange output. But if I previously finish task 11. Loops and arrays
with code (I don’t know, mb result will be same with another code)
var cities = [“Melbourne”, “Amman”, “Helsinki”, “NYC”, “”];
for (var i = 0; i < cities.length; i++) {
console.log("I would like to visit " + cities[i]);
}
and then do task 12 with code I wrote in the first post, the output has strange ending.
Looks like a bug
Thanks for your information. It seems like the test function of exercise 11 adds a new function to the array objects meaning all arrays have this new function that you can see. For a quick workaround you could just refresh the page that should get rid of this new “feature”. Anyway nothing wrong with your code and there will hopefully be a fix to this bug someday!
PS: As you can see for in loops might also reveal properties that you might not be aware of
