Typescript Language
The microsoft organization created and maintains the programming language typescript. A superset of javascript called typescript provides you with optional static typing and other programming tools. It facilitates the development of sophisticated and large-scale computer applications.
Some of the main characteristics of typescript programming are listed below.
- Optional static typing – software developers can add types to their javascript code using typescript. This makes it simpler to detect typescript issues during program compilation as opposed to during program execution.
- Support for classes, interfaces – and other characteristics of object-oriented programming in typescript. This makes writing modular, reusable code for typescript programs easier for programmers.
- Ecmascript compatibility – typescript programming is intended to be entirely compatible with the most recent version of ecmascript, the javascript-based standard.
- Tools – typescript has a variety of integrations and development tools. It makes creating, testing, and maintaining typescript apps simpler. For instance, typescript is simple to integrate with well-liked ides like visual studio code and webstorm.
- Large developer community – typescript has a huge and vibrant developer community, which means that people who utilize typescript programming have access to a wealth of tools and assistance.
What is typescript coding
A programming language with statically typed data is typescript. Which is a subset of the javascript programming language for web development. With the addition of optional static typing, object-oriented programming, features, and other features, it is intended to make it simpler to create and manage large-scale, sophisticated software programs.
Writing code that mimics javascript, the program source language is called typescript programming. However, with added syntax for types, classes, interfaces, and other constructions. The regular javascript is then produced using the typescript code. It may be run in any javascript or current web browser environment.
One of typescript programming’s key benefits is that mistakes are caught at compile time rather than at run time. The resulting program code is now simpler to develop and maintain. Because many typical program mistakes may be caught before they cause serious issues with the existing program. Additionally, typescript’s syntax and capabilities can help software engineers build clear, maintainable code and enhance the readability and maintainability of already written typescript.
What is typescript language server
Such a tool is typescript language server. It gives typescript programmers or software developers an ide (integrated development environment) to write code in and the intellectual ability to text editors. These capabilities make it easier and more productive for software developers to deal with typescript code.
A language server is one of the functionalities that typescript offers.
- Code completion – as you type typescript program code. For variables, functions, and other symbols in your code, the language server proposes completions.
- Error checking – as you write program code, the language server examines it and highlights any problems or warnings. Enabling you to quickly find errors before running your code.
- Refactoring – refactoring can be suggested and carried out by the language server. Such as changing the names of program variables, extracting functions, etc.
- Navigation – language server can aid in your codebase’s navigation. Enabling you to locate all references to a program symbol or fast navigate to its definition.
Visual studio code, webstorm, atom, and sublime text are just a few of the ides and text editors that language server is made to work with. Language server protocol (lsp), it talks with the editor. It follows a set methodology for giving out language services.
Advantage and disadvantage of typescript language
The benefits of typescript.
- Static typing – you may use static typing when writing with typescript. It increases the dependability and maintainability of your program code by making it easier to spot problems before they are executed by the program code.
- Object-oriented features – support for classes, interfaces, inheritance, and other object-oriented features is provided by typescript. As a result, writing modular, reusable code repeatedly for a program is made simple.
- Improved ide support with modern programming capabilities – typescript offers enhanced ide support with contemporary programming capabilities like intellisense, code navigation, and refactoring assistance.
- Scalability of the code – typescript programming is perfect for complex applications. Because it makes program codebases easier to maintain and manage in terms of complexity.
- Javascript compatibility – typescript is a superset of javascript programming. As a result, it is simple to incorporate already existing javascript code into the typescript codebase.
Negative aspects of typescript.
- Learning curve – explains typescript’s syntax, features, and operation to those who are unfamiliar with it. A fresh circumstance might need to be encountered in order to comprehend and learn this.
- Tooling – setting up typescript tooling might be more difficult, and you might need to configure some extra tools.
- Compile time – before being run, typescript program code must be converted into javascript program code. This may cause the cycle of program development to lag.
- Strictness – static typing in typescript may occasionally be exceedingly difficult and strict. It may result in more programming effort and complexity.
- Additional complexity – typescript can make the codebase more complicated to program. Additionally, it might not always be required. This results in more effort and maintenance costs.
Best characteristics of typescript language
Programming with typescript includes numerous important features. Making it a preferred alternative for complicated software application development.
- Object-oriented programming – support for classes, interfaces, and other characteristics of object-oriented programming is excellent in typescript. Hence enabling the writing of modular, reusable, and scalable program code simple.
- Strong typing – is supported by typescript programming. This makes it easier for developers to produce code with fewer programming errors and makes it easier to understand.
- Ecmascript compatibility – typescript is made to work with the most recent ecmascript versions. This enables integrating typescript applications with javascript code already in place simple.
- Tools – typescript has a variety of integrations and development tools. It allows the creation, testing, and maintenance of programs like visual studio code, webstorm, and others simple.
- Large community – the typescript programming language has a huge and vibrant developer community. Which offers typescript programmers assistance, tools, and libraries.

Angular typescript language service
A programming language service for typescript is called angular typescript language service. It was created especially to be used with angular apps. It enhances the entire development experience of angular apps and offers sophisticated functionality for editing and browsing angular templates.
In angular applications developed with the angular cli, the typescript language service is pre-installed. Additionally, it may be manually set in other typescript applications.
A few of the functionalities offered by the angular typescript language service are listed below.
- Type verification for angular templates – is provided by the language service. It facilitates fault detection at compilation rather than during program execution.
- Better navigation and code completion – language services offer better navigation and code completion functionalities for angular templates. For example, browsing to an angular component’s definition and auto-completion of angular directives and component attributes.
- Support for refactoring – is provided for angular templates via the language service. This makes it simple for developers to rename components, directives, and other code elements.
- Better performance – for big angular projects, the language service offers better performance. By caching the data and just re-analyzing the project’s altered portions.
Typescript code
Here is an example of a “welcome to mitacademys!” program in typescript.
console.log(“welcome to mitacademys!”);
In this example, the string “welcome to mitacademys!” is written to the console using the console.log() function. This code is also legal javascript code because typescript is a superset of javascript.
You may save this code in a test.ts file, such as test.ts, and then compile it to javascript using the typescript compiler (tsc). Run the command tsc test.ts in a terminal or command prompt after finding the directory where the test.ts file is located. A hello.js file will be generated in the same directory along with the typescript code’s conversion to javascript. Next, you may use node.js or a web browser to run the hello.js code.
As an alternative, you may execute the code without having to manually compile it by using a typescript-compatible code editor, such visual studio code or webstorm.
