TypeScript

The ultimate guide to getting started!

TypeScript is an open source programming language developed by Microsoft that is based on JavaScript and adds optional static typing to it. It was developed to facilitate the development of large and complex JavaScript applications while maintaining the advantages of JavaScript such as flexibility and dynamics.

TypeScript code is compiled into JavaScript code that can be executed in all common browsers and JavaScript engines. This means that you can use TypeScript code to develop modern web applications, mobile apps and server-side applications without having to worry about compatibility.

The advantages of TypeScript over JavaScript:

  • Static typing: TypeScript adds static typing to JavaScript, meaning that the data types of variables and functions must be explicitly declared. This can help to avoid errors and make the code easier to understand and maintain.

  • Improved tools: TypeScript offers a range of improved tools that can help developers write, debug and test their code. These include auto-completion, error checking and refactoring tools.

  • Larger code bases: TypeScript is particularly well suited to the development of large and complex code bases. The static typing and improved tools can help to avoid errors and make the code easier to understand and maintain.


TypeScript is a popular choice for the development of:

  • Web applications: TypeScript is commonly used for the development of modern web applications, including Single Page Applications (SPAs) and Progressive Web Apps (PWAs).

  • Mobile apps: TypeScript can also be used for mobile app development with frameworks such as React Native and NativeScript.

  • Server-side applications: TypeScript can also be used to develop server-side applications with Node.js.

Your FAQs to TypeScript

Welcome to our TypeScript FAQ section! Here we answer the most frequently asked questions about TypeScript to give you an understanding of this crucial implementation field.

There are several ways to use TypeScript in existing JavaScript projects:

  • Manual conversion: you can manually convert your JavaScript files into TypeScript files and then use the TypeScript compiler to compile them into JavaScript code.

  • Tools: There are several tools that can help you migrate your JavaScript projects to TypeScript step-by-step. These tools include the TypeScript Migration Tool from Microsoft and the TSLint linter.

  • Gradual introduction: You can use TypeScript first for new parts of your project and then gradually extend it to the existing code.

Yes, TypeScript can be used with most JavaScript libraries. However, there are some libraries specifically designed for use with TypeScript that can provide additional benefits. These libraries include the TypeScript Definition Files (d.ts) and the TypeScript Decorators.

You can debug TypeScript code with the same debugging tools you use for JavaScript code. Most modern development tools support TypeScript debugging, including Visual Studio Code, WebStorm and IntelliJ IDEA.

There are many resources where you can learn more about TypeScript. These include the official TypeScript documentation, various online tutorials and courses, as well as books and articles.

Yes, there is an active community for TypeScript developers. You can interact with other TypeScript developers online in forums and discussion groups and get help with problems.

TypeScript offers several ways to perform DOM manipulations. You can use the standard DOM API available in TypeScript, or you can use a TypeScript library such as TypeScript DOM, which offers additional features and benefits.

TypeScript offers several ways to manage asynchronous operations. You can use Promises, Callbacks or Async/Await. TypeScript supports all of these features and offers additional benefits such as type checking and error handling.

You can use various testing frameworks to write tests for your TypeScript code. These frameworks include Jasmine, Mocha and Jest. TypeScript offers additional advantages for writing
