Angularjs is the best thing that happens to JavaScript after jquery. This is the way JavaScript has always been developed. One of the main advantages of angular is its dependency injection (Dependency injection), which facilitates unit testing of code. But a little weird is that I couldn't find a tutorial on how to do unit tests anyway. Of course there are many good recommendations: Use the Jasmine test framework and the Karma Test executor (test Run

In JavaScript, there are two ways of defining a method.1, the method of namingfunction Add (x, y ) {return x+y;}2. Anonymous methodvar function return x+y;};In TypeScript, also compatible with the above two definitions, but, since we are using TypeScript, then certainly stronger than the original definition of the way.1, the type of methodfunction Add (X:number, Y:number): number{ return x+y;} var fun

Recently more interested in front-end testing, especially the Nodejs + Karma + Jasmine test for angular.

How to test this angular service? Using Angular.injector, call the application Module to find the service. Then it's the function of

Typescript details learning and typescript details Learning 1. Judge the type of a variable, and use typeof variable = 'array' to look like this. Note that this ''is not a single quotation mark. Remember to use three equal signs. 2. If this is passed in TypeScript and used in the callback function, you should be careful. this is not necessarily pointing to the

If Typescript is the first language in which you ' ve encountered generics, the concept can be quite difficult to understand . We Skip the lecture lesson and dive straight into a real-world use-case The need for generics.Let's say we have this part of code:class emitter{ Emit (event) { console.log (event); }} Const New '/home'true});The object we want to pass on is {path: "", Directory: ""}. But it could happen that we had some typo erro
