JavaScript learns the JS functionA function is a block of code wrapped in curly braces, preceded by a keyword function:function functionname () { Here is the code to execute}function ParametersThe parameters of a function can be arbitrarily multiple, without declaring the variable type , only by giving the variable name:function myFunction (name, job) { This is the code to execute}function return valueUsing the return statement in the functio

JavaScript learns to record Day4-map, set, and iterable[TOC]The default object representation of JavaScript {} can be thought of as a Map data structure in another language Dictionary , or a set of key-value pairs.But the JavaScript object has a small problem, which is that the key must be a string. But actually number or other data type as a key is also very reasonable.To solve this problem, the latest ES6 specification introduces new data types Map

very important thing. The basic study of the university is around the DNA in the discussion, I think that more than computer programming to abstract knowledge, so I have just graduated also very confident, will be able to learn iOS programming, learn a high-level language after learning the next assembly, computer systems and other biased knowledge, that is the foundation. You can also learn the latest go language, but also a kind of inspiration for themselves.Career change is hard, but after t

I. Java reflection mechanismunderstand the principle of the Java reflection mechanism firstExample online a lot, reflection is very flexibletwo. Tune Java at the JNI layeruse:Java layer reverse is relatively easy, increase the reverse threshold, the call is written to the JNI layer, so that the Java layer has no call relationshipNote:C and C + + are different, use C + + as an example here1. First provide a showlog function in the code private void showmsg () { Log. D ("_bing_", "showmsg");}2. A

string*Swift's string type is seamlessly bridged with the Foundation NSString class*the strings in the OC language are also terminated with a, Swift is not*The string in OC is an object, and Swift uses string as a struct, which is more efficient and supports traversal attention* Swift's string type is a value type. If you create a new string, then it is a constant, variable assignment operation, or a function/when passed in a method, a value copy is made. In any case, a new copy of the existing

Java learns 22nd from scratch (Set Interface), set from scratch1. Definition of the Set interface is also a sub-interface of the Collection interface. However, unlike the Collection or List interface, duplicate elements cannot be added to the Set interface. The main methods of the Set interface are the same as those of the Collection interface. The instance of the Set interface cannot perform bidirectional output like the List interface. The get me

overrideableComputedTypeProperty: Int {return 107}}Attention:The computed Type property in the example is read-only, but you can also define a readable and writable computed type property, similar to the syntax for an instance-computed property.2.5 Getting and setting the value of a Type propertyAs with the properties of an instance, access to the Type property is done through the dot operator. However, the Type property is obtained and set through the type itself, rather than through the insta

whole C language, as the teacher said, if the pointer did not learn well, C language learning is also equivalent to not learning C, visible pointers in C language learning importance, and this chapter mainly learn the definition and use of pointers to pointers, pointers and arrays , pointers and strings, pointers to functions, etc., which focus on pointers and arrays as well as pointers and strings, these two knowledge points are equivalent to integrating the entire knowledge of this chapter in
