Concatenating Strings with Plus Operator spaces

JavaScript
1

Tell us what’s happening:
Why on earth is there a space after the dot after ‘start’, but no space after the dot after ‘end’?
It’s inconsistent and confusing. Is there any logical explanation for this?

Your code so far


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

// Only change code below this line

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

If you removed that space, concatenating the strings will result in

"I come first.I come second"

The space is there so the sentences are separated after concatenation.
