For:is a value pass. Method calls in the Java language only support value passing of parameters. When an object instance is passed as a parameter to a method, the value of the parameter is a reference to the object. The properties of an object can be changed during the call, but changes to the object reference do not affect the caller. In C + + and C #, you can change the value of an incoming parameter by passing a reference or transmitting a paramete
var v1 = []var v2 = {};var v3 = {};function foo (v1, v2, v3) {V1 = [1];v2 = [2];V3 = {A:3}}Foo (v1, v2, v3);Alert (v1); BlankAlert (v2); [Object Object]alert (V3.A); Undefined/* This shows: v1, V2, V3 have not been changed, V1 is still an array of 0 elements, V2, V3 is still a blank object. (description is not a reference pass)* However, arrays, objects, etc. are passed by value, which refers to the value of the variable address.* The values of arrays

The General data type (int, float, bool) does not explain this.Here is a detailed description of the difference between an array and the object of a class as a parameter for value passingArray value passingInstance code: output: array(2) { [0]=> string(1) "a" [1]=> string(1) "b" }Array reference passingOutpout:array (1) { [0]=> string (2) "DD"}Class Object Value passingOutput:object (PP) #1 (1) { ["ss"]=> Int (10)}Class object reference passingObject (PP) #1 (1) { ["ss"]=> Int (10)}
