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 example and be sure to include a space between the two strings.
Start by assigning the first string to myStr, then add on the second string.

- myStr should have a value of the string This is the first sentence. This is the second sentence.
- You should use the += operator to build myStr.

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