1. Introduction of ANGULAR2 predefined types Import {Component,View,Bootstrap} from "Angular2/angular2" ;2. Implement a ANGULAR2 component @Component({selector:"Ez-app"})//location rendered to using the CSS selector via the Selector property @View({template:' } ')//view, specify the rendered template through the Templates property Class Ezapp{} 3. Rendering components to the DOMbootstrap(ezapp);
Besides @Input (), we can also use properties on the @Component, to pass the data.Import {Component, View, Ngfor, Input} from ' Angular2/angular2 '; @Component ({selector:' Reddit-article '}) @View ({directives: [], Template: ' `}) Export class Redditarticle {@Input () article:article; Voteup () { This.

Kotlin Learning (2) -- basic syntax, function, variable, string template, conditional expression, null, type detection, for, while, when, interval, set, kotlinnull1. Basic syntax
Many concepts of Kotlin are similar to those of JAVA, so I should not be as detailed as I did on my JAVA journey, but don't worry, you will understand it, I also learned from official documents.
Create a project Kotlin02 in IDEA1.

Title: Seek 1+2+...+n, the request cannot use multiplication and division method, for, while, if, else, switch, case and so on keyword and conditional judgment statement (A? B:C)
This problem is indeed a bit biased, most people on the internet to give the solution are recursive. public int sum (int n) {if (n==1)
return 1;
Else
Return N+sum (n-1);
Obviously, the condition is used to judge, does not meet the
