then (a and B) or c. under normal circumstances, if a is true, a and B will return B. If B is a string or value, it is 'true'. Therefore, B or c will return B directly, design that meets the expectation of "a is true, returns B.
However, if B is a variable and the variable is null (for example, not defined), B is false, and B or c returns c. in this case, "a is true, but c is returned.
Therefore, in order for expression a and B or c to work normally, B must be true. if B is not true, only if-el
