TypeScript nameof

TypeScript is all about making JavaScript scale intelligently. nameof is just one of the tricks in the book that makes life a little easier when you want the type safety of knowing that the string you type is a property on a given object This is especially useful in TypeScript when using jQuery plugins ( Bootstrap-Tagsinput) or other libraries where the name of a property needs to be configured. It could look like: const name: string = nameof (Console.log); // 'name' is now equal to log ts-nameof. nameof in TypeScript. Monorepo for ts-nameof projects: ts-nameof (TypeScript compiler) babel-plugin-ts-nameof (Babel compiler) ts-nameof.macro (Babel compiler) Setup. ts-nameof is a compile time transform so it requires some setup. For setup instructions, see the packages above for the compiler you use. nameof transform nameof(... In C# 6, you can use the nameof operator. This is very useful. However, this is not possible in TypeScript yet. Many issues are asking to support this operator. In the meanwhile, you can create a function that simulates the nameof operator, at least for the most common case, using the keyof operator. function nameof<T>(key: keyof

I would like to see the nameof operator be considered for Typescript. This feature was just added to C# description, and it is an elegant solution to a common issue in Javascript. At compile time, nameof converts its parameter (if valid), into a string. It makes it much easier to reason about magic strings that need to match variable or property names across refactors, prevent spelling mistakes, and other type-safe features

Enumerated data types (enums) are a set of numeric values with more friendly names. It's an addition on top of JavaScript that TypeScript offers Introduction to TypeScript Getters and Setters. The following shows a simple Person class with three properties: age, firstName, and lastName: class Person { public age: number ; public firstName: string ; public lastName: string ; } Code language: TypeScript (typescript) To access any property of the Person class, you can simply do like this Function.name. A Function object's read-only name property indicates the function's name as specified when it was created, or it may be either anonymous or '' (an empty string) for functions created anonymously.

in .NET, it's easy to get the class name of an object using obj.GetType().Name. In JavaScript, this doesn't work: typeof obj return object or something else, but never the name of the class. This doesn't mean you cannot get the name of a class in JS. In ES6, you can use Function.name to get the name of a function (documentation). function test() { } console.log(test.name); // print test. ts-nameof is a compile time transform so it requires some setup. For setup instructions, see the packages above for the compiler you use TypeScript provides several utility types to facilitate common type transformations. These utilities are available globally.

TypeScript provides some nice features on top of the JavaScript such as static typing. In this post, we are going to cover one of these TypeScript features, the private keyword. ES2015 Classes . Before we dive into TypeScript's private feature let's do a quick recap of JavaScript classes That means that if you misspell the name of a member or you change a method name later that nameof pointed to, you'll know about it as soon as you try to build. This means that when you use the nameof operator, you're no longer in danger of using a misspelled or out-of-date string. Okay, I get it. You probably don't do any XAML-based. Intro Linq in c# is a great abstraction, it massively reduces the amount of code to do fairly basic operations, using TypeScript doesn't mean you lose this functionality, its just a little different to achieve many of the operations. In this article I'll run through the basic Linq-To-Object operations, and how you can achieve similar results in TypeScript

`nameof` just returns a string representation of the static symbolic name of its operand. `nameof` would be used at runtime (i.e. during code execution), but provides the ability for advanced editors to include it in a rename refactoring. The operand merely needs to be an identifier that exists within the current lexical scope. `nameof` would not observe TDZ and would not evaluate any.

TypeScript 4.0 Beta TypeScript 3.9 just shipped about seven weeks ago, featuring faster compile times and much more. Now it's on to v4.0 for the dev team, with program manager Daniel Rosenwasser reassuring developers the new release won't contain any more breaking changes than usual. Our philosophy in evolving TypeScript has always been to provide an upgrade path that minimizes disruptive. Using TypeScript transforms we can only have a backend transformer allowing us to perform modifications on the existing AST. AST basics. The AST is a tree that consists of nodes representing groups of syntax information and edges representing their relationships. For instance, a trivial example code like this: const a = 3 + 4; console.log(a); transforms into an AST like this: { type.
