Awesome FP JS This is a curated list of awesomefunctional programmingcode and learning resources for JavaScript. As a multi-paradigm programming language, JavaScript can be written in many styles. With these resources we want to help you to make better use of JavaScript’s support for writing pr...
Dependency injection makes circular references more explicit and therefore safer than vanilla ES6 or CommonJS. If two classes depend on each other, you can define a method to be executed right after the constructor. Any class you depend on within the post-constructor can be successfully instantiate...

TypeScript 并不支持高阶类型，因为 TypeScript 中的泛型不属于类型，泛型的参数必须是具体类型，不能是...
constructor(fn) {this.$value =fn; } map(fn) {returnnewIO(compose(fn,this.$value)); } inspect() {return`IO(${this.$value})`; } } IO will take a function as input. Example of IO: ( Note: the reuslt shown in comment is not actual result, the actual result is wrapped in {$...
By using a switch statement on the constructor, we can get direct access to the type of error before mapping it to the correct Express.js HTTP response code. Composing the controller with the use case In order to use this controller in our app, we need to create it and then export it...
The implementation consists of a constructor expression for a string table (line 4). Using the FOR iterator expression the values form 1 to 100 are passed to a COND expression. The COND expressions uses a LET expression to create two local variables r3 and r5. r3 and r5 store the result...

Higher Kinded Typesallow us to use atype constructorin our type parameters, which looks likeC[_]. This is a way of saying that whateverCis, it must take a type parameter. For example: trait Foo[C[_]] { def create(i: Int): C[Int] ...
