Concatenating Strings with the Plus Equals Operator help

**Tell us what’s happening
I need help, finding the solution to this challenge. i don’t know what I missed here.

Your code so far

// Example
var ourStr = "I come first. ";
ourStr += "I come second.";

// Only change code below this line

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

Link to the challenge:

You need a space between the sentences.

im not understanding. i guess i dont see it.

At this point in this your code is console logging

This is the first sentence.This is the second sentence.

It needs to logging the sentences separated with a space. Like this:

This is the first sentence. This is the second sentence.

should it be in one string or two?
i have it written like this:

var myStr = “This is the first sentence.”;

myStr += “This is the second sentence.”;

Read carefully what they are asking you. Look at the first string, it is not the same as your first string.

Build myStr over several lines by concatenating these two strings:
"This is the first sentence. " and "This is the second sentence." using the += operator. Use the += operator similar to how it is shown in the editor. Start by assigning the first string to myStr , then add on the second string.
