If I have the logic "if expr is true call function b" (where expr is some expression), which of the following is preferred as the "most readable" style? Is there another good reason to choose one over the other? 
expr && b();  # Short circuit operator
b() if expr;  # if clause
if ( expr ){  # "traditional" if
    b();
}
