we've assigned values for V1, V2, v3, which means we've changed the point of the address copy to a new array and object. Such internal v1, V2, v3 and external v1, V2, v3 are completely broken.If we do not assign a new value, but instead manipulate it directly, then it is still the same array or object that the outside V1, V2, V3 point to.var v1 = []var v2 = {};var v3 = {a:0};function foo (v1, v2, v3) { V1.push (1); v2.a = 2; v3.a = 3;} Foo (v1, v2, v3); alert (v1); 1alert (v2.a); 2aler

From the beginning of C language sometimes to tell some details or the bottom of things, I like to use C language, because C more convenient to describe the memory of things. To give an example, the swap function, I believe that some programming experience people have seen, the statement is as follows, the function body I will not write, you brain to fill. void Swap1 (int A, int b); void Swap2 (int* A, int* b) Here Swap1 is unable to exchange two number of values, SWAP2 can.

Tips for Improving the method of passing PHP function parameters. After writing the code for repeated operations, we decided to improve the traditional PHP function parameter passing method and use arrays as parameters. See the following example. first, let's look at a traditional self-built system.After repeated opera

', age:25} In a non-pure function changeAgeImpure , the object person is age updated and returned. The original alex object is also affected, age updated to 25.Let's see how to implement a pure function: function changeagepure (person) {var newpersonobj = Json.parse (json.stringify (person)); Newpersonobj.age = + ; return newpersonobj;} var alex = {name: ' Alex ',Age: +}; var alexchanged = changeagepure (Alex); Console.log (Alex); //{name: ' Alex ', age:30} Consol

Passing parameters by value and reference in C # (Downmoon)In C #, parameters can be passed either by value or by reference. Passing parameters by reference allows function members (methods, properties, indexers, operators, and constructors) to change the value of the parame

In C #, parameters can be passed either by value or by reference. Passing parameters by reference allows function members (methods, properties, indexers, operators, and constructors) to change the value of the parameter and maintain the change. To pass parameters by reference, use the ref or out keyword. For the sake o

the consistency check will be performed for function passing parameters, and the type of parameters will be checked for how many parameters you pass. However, the preceding example shows that javascript does not have such consistency check! It seems that he can accept multi
