JS NICE: Statistical renaming, Type inference and Deobfuscation
Welcome to JSNice — we make even obfuscated JavaScript code readable. We will rename variables and parameters to names that we learn from thousands of open source projects. Furthermore, often we are also able to guess or infer type annotations. Try JSNice on your JavaScript code to see how it works! Override the names suggested by JSNice (by enabling "interactive renames" in settings). Click to le

Effective TypeScript › Flow Nodes: How Type Inference Is Implemented
In most programming languages a variable has a type and that type does not change. But one of the most interesting aspects of TypeScript's type system is that a symbol has a type at a location. Various control flow constructs can change this type: function refine(x: string | number) { // type of x is string | number here if (typeof x === 'number') { // type of x is number here. } else { // type of
Introduction Java SE 10 introduced type inference for local variables. Previously, all local variable declarations required an explicit (manifest) type on the left-hand side. With type inference, the explicit type can be replaced by the reserved type name var for local variable declarations that have initializers. The type of the variable is inferred from the type of the initializer. There is a ce

Chapter 16 Hindley/Milner Type Inference - プログラミング言語 Scala Wiki
Chapter 16 Hindley > Milner Type Inference 第 16 章 Hindley/Milner 型推論 (Hindley/Milner Type Inference) この章では、Hindely/Milner スタイル[Mil78] の型推論システムの開発を通して、Scala のデータ型とパターンマッチングを見てみます。型推論器の対象言語は、mini-ML と呼ばれる let 構成子を持つ λ計算です。mini-ML の抽象構文木は、次のデータ型 Term によって表現されます。 abstract class Term {} case class Var(x: String) extends Term { override def toString = x } case class Lam(x: String, e: Term) extends Term
JS 実装をしようかな、と思い立ち、 まずは型推論の知識をしっかり取得するところから初めようと考えています. そもそも、型推論とはなんぞや、というところからおさらいしてみます. 私が型推論について知りたいことの一番の目的は、 「型推論を行うことで動的言語の事前コンパイルを可能にしプログラムの実行を早くすることができるのではないか」, ということになりますので、それに特化した内容になっています. もちろん型推論には、プログラムを早くするという以外の目的もありますが、 ここではそれらは取り上げないことにします. 型推論(type inference)とは、簡単に言うと、 var muda = 7 というコードがあったら、 「変数 muda って Int 型(整数型)じゃね？」 とコンパイラがよろしく変数の型を決定してくれる(推測してくれる)機能になります. 静的な関数型言語(Ocaml, Ha
Summary Enhance the Java Language to extend type inference to declarations of local variables with initializers. Goals We seek to improve the developer experience by reducing the ceremony associated with writing Java code, while maintaining Java's commitment to static type safety, by allowing developers to elide the often-unnecessary manifest declaration of local variable types. This feature would

Type inference - Wikipedia
Type inference, sometimes called type reconstruction,[1]: 320 refers to the automatic detection of the type of an expression in a formal language. These include programming languages and mathematical type systems, but also natural languages in some branches of computer science and linguistics. Types in a most general view can be associated to a designated use suggesting and restricting the activi

Adam Gundry, Conor McBride and James McKinna We consider the problems of first-order unification and type inference from a very general perspective on problem-solving, namely that of information increase in the problem context. This leads to a powerful technique for implementing type inference algorithms. We describe a unification algorithm and illustrate the technique by applying it to the famili
The type inference algorithm is based on the CFA2 control-flow analysis. Currently, it handles core JavaScript only (DOM support will be added soon). For comments and suggestions, email: dimvar at ccs dot neu dot edu.
Type Inference brings JS improvements to Firefox Beta – Future Releases
Blog by Brian Hackett, Firefox Engineer Firefox 9 features the release of Type Inference, or TI, a research project under way for over a year. TI is a feature in the SpiderMonkey Javascript engine which generates type information about Javascript programs through a combination of analyzing the program’s code and monitoring the types of values as the program executes. This type information is used

Type Inference Was a Mistake
Type inference is bad. It makes code harder to read, and languages that use it too much are harder to write. It’s a false economy whereby you save unobservable milliseconds of typing today and make everything else worse. Type Inference Makes Code Less Readable If you have an IDE with a working LSP, you can hover over variables to see their types. In VSCode with rust-analyzer I can see the type ann
Adam Gundry This thesis studies questions of type inference, unification and elaboration for languages that combine dependent type theory and functional programming. Languages such as modern Haskell have very expressive type systems, allowing the programmer a great deal of freedom. These require advanced type inference and unification algorithms to reconstruct details that were left implicit, and

Java Has Type Inference and Refinement Types (But With Strange Restrictions)
When enthusiasts talk about Scala they frequently start with "it's a lot like Java but with all this other cool stuff like type inference and structural types and..." I guess it's okay to introduce Scala that way. I've done it myself. But it does give the impression that Scala has somehow heaped complexity onto the Java. Oddly enough, it hasn't, at least not in the areas of type inference and stru

What type inference algorithm does the Go compiler use? I tried looking this up on golang but I can't find documentation. I am tempted to assume that it would be Hindley-Milner, but I would like to know for sure
