1. In JavaScript, the arguments object is a more specific object, which is actually a built-in property of the current function. Arguments is very similar to an array, but is not actually an array instance. Can be confirmed by the following code (of course, in the function Funcarg, the call arguments is not necessarily written funcarg.arguments, write arguments directly).1 ARRAY.PROTOTYPE.TESTARG = "Test";

MySQL 5-1 -- index bitsCN.com 1. MySQL has multiple rows that access tables. The most commonly used is sequential access and index access. Sequential access refers to browsing a table in one row, that is, full table scan. Disadvantage: it is very time-consuming and inefficient. Index access: read only the rows that show the required features, including at least o
