Basic JavaScript - Concatenating Strings with Plus Operator

I don’t know what I’m doing wrong, it keeps saying:
myStr should have a value of the string This is the start. This is the end.

Your code so far

const myStr =  "This is the start. " + "This is the end. ";

Did they ask for the space at the end of the string? Or only in between?
