如果radix 是undefined 或0(或沒寫), JavaScript 會假定: If the input string begins with "0x" or "0X", radix is 16 (hexadecimal) and the remainder of the string is parsed. If the input string begins with "0", radix is eight (octal) or 10 (decimal). Exactly which radix is chosen is...
The comma operator has the lowest precedence of all operators. If you want to incorporate a comma-joined expression into a bigger expression, you must parenthesize it. The comma operator is completely different from commas used as syntactic separators in other locations, which include: Elements in...

在一个表达式中进行多个运算时,每一部分都会按预先确定的顺序进行计算求解,这个顺序被称为运算符优先级。括号可改变优先级的顺序,强制优先处理表达式的某部分。括号内的操作总是比括号外的操作先被执行。但是在括号内,仍保持正常的运算符优先级。 当表达式有多种运算符时,先处理算术运算符,接着处理比较运算符,然后...
The comma (,) operator evaluates each of its operands (from left to right) and returns the value of the last operand. This is commonly used to provide multiple updaters to a for loop's afterthought.
