Tell us what’s happening:
I can’t see what is wrong with my code.

Your code so far

// Only change code below this line

var myStr = " This is the first sentence.";
myStr +=  " This is the second string.";

Challenge: Concatenating Strings with the Plus Equals Operator

Link to the challenge:

careful with spaces, do you ever write a sentence putting a space before everything else? or do you usually put a space as first character?
spaces usually go only after words and punctuation


I think in this challenge, myStr should have a value of This is the first sentence. This is the second sentence.
So as @ilenia pointed out, I suggest removing the first space in the first sentence and also replacing the word "string" in your second sentence with "sentence".
