, 逗号运算符 优先级从上到下依次递减,最上面具有最高的优先级,逗号操作符具有最低的优先级。 所有的优先级中,只有三个优 先级是从右至左结合的,它们是单目运算符、条件运算符、赋值运算符。其它的都是从左至右结合。 具有最高优先级的其实并不算是真正的运算符,它 们算是一类特殊的操作。()是与函数相关...

Because of operator precedence, this would be the same as x = Fred[0] + 42; Perfectly legal code, and a potentially hellish bug to track down. This is why we use the square brackets -- it replaces two operations with one so that we don't have to get tripped up by the precedence...
