问题 A period of intense googling provided me with some examples where people use both types of operators in one code, but generally they look just like two ways of doing one thing, they even have the same name 回答1: tl;dr: The defining difference is that -> pipes to the first argument while |> pipes to the last.

问题 What are the tradeoffs between ReasonML (https://reasonml.github.io/) and TypeScript (https://www.typescriptlang.org/)? 回答1: There are lot of languages nowadays that target JavaScript. Choosing one of them depends on your needs and the idioms you're comfortable with. JavaScript has a dynamic type system. Some developers prefer a static one. TypeScript or Haxe solves this with a new language that is statically typed and only transpiles to JavaScript. Flow is a JavaScript preprocessor that
