I have a string that looks like this:
"a "
As you can see there is only one character that is not empty " ". How do I remove the last charaters of the string so only the valid one(s) will remain:
"a"
This can also be considered in cases where the first characters are empty:
" a"
I cannot simply remove each empty key as they can be part of a more complex sentence like this:
"I love Js "
In order to be able to remove easily the trailing spaces
I suggest that you use the trim() method.
a '.trim() // return 'a'
