Explain why the result of
('b' + 'a' + + 'a' + 'a').toLowerCase()isbanana.
In an arithmetic operation, if an operator is preceded by a blank space or nothing and is followed by a non-numeric value like a string or character, the result is NaN (Not A Number).
'b' + 'a' + + 'a' + 'a' can be interpreted as 'b' + 'a' + (+ 'a') + 'a' where (+ 'a') is evaluated as NaN.
'b' + 'a' + + 'a' + 'a' is evaluated to "baNaNa", which is turned to lowercase "banana" when fed to the .toLowerCase() function.
