You can get the number of digits in a JavaScript number in the following ways: Converting to String and Checking the length;
String变量被初始化后,长度和内容都不可变,每次对String的操作都会生成新的String对象,不仅效率低,而且耗费大量内存空间;对于String str = new String(“abc”),实际上创建了两个String对象,一个是”abc”对象,存储在常量空间中(常量池),一个是使用new关键字为对象str申请的空间。 Integer i1 = new Integer(1)...
