Compares two strings after normalizing them. This operation is case insensitive.
"Normalize" means that _.stringNormalize() is called, which if the variable passed is null or undefined an empty string is returned, otherwise the result is trimmed of leading and trailing whitespace.
- Calling Convention:
- Your strings to be normalized and compared.
- -1 if first string is alphabetically lower than the second
- 0 if the two strings are equal
- 1 if first string is alphabetically higher than the second
The various compare functions stored in elementals are meant as easy callbacks for use with _.USort.element.
