Get a version of the String with any leading and trailing whitespace removed. As of 1.0, trim() modifies the String in place rather than returning a new one.
- myString: a variable of type String.
The result on Serial Monitor:
As we can see, the length of the myString before trimming is 10. After trimming, the length is 7. That is because one leading and two trailing whitespace charecters are removed.
※ NOTES AND WARNINGS:
If the string is modified, it is highly recommended using String.reserve() to prevent the memory fragmentation issue
