Typescript Development Services

TypeScript is a programming language developed by Microsoft that adds static typing to JavaScript. It is designed to address some of the shortcomings of JavaScript, making it more scalable and maintainable for large applications. The language was first released in 2012 and has since gained popularity among developers for its ability to catch errors during development, improve code navigation and refactoring, and enhance overall code quality.

At its core, TypeScript is a superset of JavaScript, which means that any valid JavaScript code is also valid TypeScript code. This makes it easy for developers familiar with JavaScript to transition to TypeScript gradually. TypeScript introduces static typing, allowing developers to specify the types of variables, function parameters, and return types. This additional layer of information helps catch common errors at compile-time rather than runtime, providing a more robust development experience.

Unknown Facts About TypeScript

String Literal Types

TypeScript supports string literal types, allowing developers to define types that accept only specific string values. This feature enhances code readability and reduces the likelihood of introducing errors related to incorrect string values.

JavaScript Superset

TypeScript is designed as a superset of JavaScript. This means that any valid JavaScript code is also valid TypeScript code. Developers can start using TypeScript by gradually adding type annotations to their existing JavaScript projects, allowing for an incremental adoption of TypeScript features without the need for a complete codebase rewrite.

Compiler-Driven Development

TypeScript's static type system is at the core of its design philosophy. The TypeScript compiler analyzes the code and provides feedback during development. This compiler-driven development approach catches potential errors early in the process, offering a proactive strategy for maintaining code quality and reducing runtime issues.

Conditional Types

TypeScript introduces conditional types, a powerful feature that allows developers to express more complex relationships between types. Conditional types enable the creation of type definitions that depend on conditions, leading to more flexible and expressive type systems.

TypeScript Playground

The TypeScript Playground is an online tool provided by the TypeScript team. It allows developers to experiment with TypeScript code in a web-based environment. The playground provides instant feedback on type checking and transpilation, making it a valuable resource for learning TypeScript concepts and trying out code snippets.

Strict Null Checks

TypeScript introduces strict null checks to help catch common programming errors related to null and undefined values. When strict null checks are enabled, variables are by default considered non-nullable unless explicitly specified otherwise. This feature enhances code safety by preventing unintended null or undefined values from causing runtime errors.

Declaration Files and DefinitelyTyped

TypeScript uses declaration files (.d.ts) to provide type information for existing JavaScript code and libraries. These files describe the shape and types of the code, enabling TypeScript to perform type checking. The DefinitelyTyped repository on GitHub is a community-driven effort to provide declaration

Origin and Development

TypeScript was developed by Microsoft and was first announced by Anders Hejlsberg, known for his work on C# and Turbo Pascal. It was introduced to the public in October 2012. The language has since evolved with regular updates, and its development is overseen by the TypeScript team at Microsoft.

Mapped Types

Mapped types in TypeScript provide a way to create new types based on the properties of existing types. This feature is particularly useful for scenarios where developers need to transform or manipulate the properties of an object type in a generic and reusable way.

Integration with Popular Frameworks

TypeScript has gained widespread adoption in the web development community and is integrated into popular front-end frameworks. Angular, a widely-used web framework developed by Google, is built with TypeScript.

Why Choose TypeScript

Static Typing

TypeScript introduces static typing, allowing developers to specify the types of variables, function parameters, and return types. This is a departure from JavaScript, which is dynamically typed. In dynamic typing, variable types are determined at runtime, which can lead to runtime errors that are challenging to catch during development.


TypeScript supports interfaces, which allow developers to define the shape of objects. Interfaces are particularly useful for ensuring that objects conform to a specific structure, promoting consistency in code.


TypeScript incorporates class-based object-oriented programming features, making it easier to organise code in a modular and reusable manner. Classes provide a blueprint for creating objects, encapsulating data and behaviour within a single unit.

Compiling to JavaScript

TypeScript code is not directly executed by browsers or JavaScript engines; it needs to be transpiled into JavaScript. The TypeScript compiler (tsc) performs this task. The compilation process involves checking types, applying language features, and generating JavaScript code that is compatible with various JavaScript environments.

Type Checking

The TypeScript compiler performs static type checking by analysing the code for type-related errors. If it finds any inconsistencies, it reports them as compilation errors, preventing potentially problematic code from reaching the runtime environment.


Once the type checking is successful, the TypeScript code is transpiled into JavaScript. This process involves translating TypeScript-specific syntax and features into equivalent JavaScript code. TypeScript supports various ECMAScript versions, and the target ECMAScript version can be specified in the tsconfig.json configuration file.

Output Generation

The transpiled JavaScript code is then generated in one or more output files, depending on the project configuration. The generated JavaScript is what is ultimately executed by browsers or other JavaScript environments.

File Extension

TypeScript files typically have a .ts extension. Developers can rename existing .js files to .ts to start the conversion process. The TypeScript compiler recognizes both file types.

Type Definition Files

For JavaScript libraries or code without TypeScript declarations, developers can use type definition files (.d.ts). These files provide type information for existing JavaScript code, enabling TypeScript to understand the types used in external libraries.

Gradual Adoption

Developers can gradually add type annotations to existing JavaScript code, improving type safety and catching potential errors. TypeScript's incremental adoption allows teams to experience the benefits of static typing without a significant upfront investment.

Visual Studio Code Integration

Visual Studio Code, a widely used code editor, has built-in support for TypeScript. It provides features such as Intelligence for autocompletion, error checking, and inline documentation, enhancing the development experience.

tsconfig.json Configuration

TypeScript projects are configured using a tsconfig.json file. This file specifies compiler options, including the target ECMAScript version, module system, and other settings. It allows developers to customise the TypeScript compiler behaviour for their specific project requirements.

Declaration Files

TypeScript relies on declaration files (.d.ts) to provide type information for JavaScript code and libraries. These files describe the shape and types of the existing JavaScript code, enabling TypeScript to perform type checking.

npm and Package Management

TypeScript projects often use npm (Node Package Manager) for package management. Many popular libraries and frameworks have TypeScript type definitions available through npm, allowing developers to benefit from static typing when using external dependencies.

Early Error Detection

TypeScript's static typing enables early error detection during development, reducing the likelihood of runtime errors in production.

Code Readability and Maintainability

Type annotations and interfaces improve code readability and maintainability. They serve as documentation, making it clear how functions and objects are intended to be used.

Tooling Support

TypeScript integrates seamlessly with modern development tools, providing features such as autocompletion, code navigation, and refactoring support. This enhances developer productivity.


For large codebases, TypeScript's static typing and object-oriented features contribute to better code organisation and scalability.

Learning Curve

The transition from JavaScript to TypeScript may involve a learning curve, especially for developers new to static typing and object-oriented programming concepts. Build Process Overhead: The additional step of transpiling TypeScript to JavaScript introduces a build process, which might be perceived as overhead, especially for small projects.


Community Adoption

While TypeScript has gained significant popularity, there are still projects and communities that predominantly use JavaScript. This dual ecosystem might pose challenges for developers working on mixed codebases.

Tooling Configuration

Configuring the tsconfig.json file and managing TypeScript compiler options might be daunting for beginners. However, it's a one-time setup that provides project-specific customization.
