Question :
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.
My attempt :
var myStr = "This is the first sentence. "
myStr += "This is the second sentence. "
What seems to be the problem???
