What is TypeScript?

TypeScript is a free, open-source, high-level programming language developed by Microsoft in 2012. Anders Hejlsberg, the creator of TS, is also known as the father of C# language. It is also referred to as JavaScript superset. Why? Because any legitimate JavaScript code is also a legitimate TypeScript code.

All in all, TS expands JS capabilities with features like optional static typing and new data structures such as Classes and Enums, making developers shift from JavaScript to TypeScript. One of the most significant advantages of TS is its active developer community, which creates libraries that help streamline developers' work. As a result, developers today prefer TypeScript web development.

The main goal of this language is to present a robust type of system for JavaScript users. It enables top-down TypeScript types that define developer-defined variables to facilitate the development of complex, scalable, and large apps. TypeScript developers embrace using this language because of its seamless integration with existing JavaScript projects and the potential it offers through static typing and flexibility.

What Are the Features of TypeScript?

TS provides valuable features to streamline development, testing, and application maintenance. The following are some significant TypeScript features:

• Interfaces - This feature helps the programming language specify the objects' structure. They enable you to determine the expected data structure, which makes it effortless to build clean contracts between various application components.

• Static Typing - This TypeScript feature allows you to determine data types for objects, functions, and variables, assisting in error detection during compilation. It also enables TypeScript developers to recognize and rectify any potential loopholes faster.

• Decorators - These specific constructs enable you to extend or modify properties, methods, and classes of objects. They promote clean, easily expandable code development.

• Classes and Inheritance - TypeScript development introduces and uses classes and inheritance because of their familiarity with C# and Java.

• Incorporation of Development Tools - Hands down - one of the best TypeScript features! It incorporates popular developer tools like Linters, WebStorm, and Visual Studio Code. It streamlines the application development process and supports various working environments.

• Modules - TS is developed using different modules, making it easy to build multiple independent application parts without importing extra components.

Understanding The TypeScript Types

The popular programming language has various basic types, like Tuples, Array, String, Number, Boolean, etc. A few of these don't even exist in JavaScript. Hence, mentioned below are some critical TypeScript types:

• Intersection and Union Types - These help you build custom types that fit your logic smoothly. Moreover, intersection types allow you to imbibe different basic types into one type.

• Never - Never is referred to as the return type for something that should never happen, for instance - a function throwing an exception.

• Void - Developers use this TypeScript type when no value is returned, for instance, like the return type of functions that return nothing.

• Any and Unknown - While any as a type can include, well, anything you desire, unknown is its type-safe fellow. Unknown is akin to any, but it won't let you execute any operations on the variable before it is type-checked.

What is TypeScript Used For?

You can use TS in several projects, both for the frontend and backend. The recent advancements in TypeScript also enable you to build top-notch web applications, developer tools, frameworks, libraries, and games. Organizations working on large and complex projects today deploy TS services. And why? Because TypeScript types and its features help with code organization and maintenance.

One of the most popular reasons to use the language is that it helps build apps based on different frontend frameworks like Vue, React, or Angular. TypeScript development also allows good command over component behavior and data types, which results in more reliable apps.

Moreover, you can also opt for TypeScript services to develop server-side applications built on the Node.js platform, employing the same language for backend and frontend development.

Why is TypeScript Better Than JavaScript?

TypeScript's mantra - JavaScript that scales! TS is revolutionizing the future of JavaScript development and is now 6th on GitHub pull requests for Q4 2023.

But is it as revolutionary as techies state? Is TS better than JS? The following section is your answer.

• More Explicit than JavaScript - With explicit types, you can focus on how your system has been developed and how its different components interact. In extensive systems, it is crucial to abstract away the remaining part of the system while considering the conditions. And different TypeScript types will help you do that.

• TS and JS are Quite Interchangeable - TS is the JS superset. Hence, you can utilize JavaScript code and libraries during your TypeScript development. Simply stated, you can steadily leverage TypeScript features in your JavaScript codebase.

• Better Reliability - When debating TypeScript vs JavaScript, TS code is seamless to refactor, eventually making it more reliable. TypeScript developers can easily avoid errors and rewrite code.

What Are the Major Advantages of TypeScript for Developers?

In the context of software development, following are some significant benefits of TS:

1. Readability - Thanks to some TypeScript features like strict types that make your code more self-expressive. A self-explanatory code can quickly address the lack of open communication between the team members.

2. Optional Static Typing - Strong static typing is one of the best advantages of TypeScript. Once you declare a variable, it only takes specific values and cannot change its type.

3. The Power of OOP Paradigm - TypeScript development very well supports Object-Oriented Programming (OOP) notions like inheritance, interfaces, classes, etc. The OOP model helps to create systematic, scalable code.

4. IDE Support - The type details render integrated development environments (IDEs) and editors much more efficiently. They provide crucial features like auto-complete and code navigation, eventually giving accurate suggestions.

5. Integrated Support for ECMAScript Versions - The updated versions of ECMAScript, like those in the TypeScript 4.7 release, provide control flow analysis and ESM support for Node.JS 16. They also act as a scripting language that shapes the JavaScript base.

6. Top-Notch Community Support - Behind the ample advantages of TypeScript, a vast, talented community of deeply knowledgeable individuals work non-stop to optimize the language.

What Are Some Limitations of TypeScript?

There are ample advantages to TS; however, it comes with some limitations, too. First of all, you can't just pick a JavaScript repository or JavaScript team and directly change them to idiomatic TS. There are upfront time losses and several tradeoffs you need to make.

While we can debate about the specific long-term savings that TypeScript types offer, for the short term, its addition consumes more time. This is not a grand bargain but a point in JavaScript's favor.

Therefore, choosing TypeScript development for small prototypes and projects may not be the best idea.

How to Implement TypeScript in Your Software Project?

We're pretty sure, by now, you already have an idea of what is TypeScript, what is TypeScript used for, its advantages, and how it makes developers' lives easier. But the most crucial question - is how to implement it.

So, to implement TS, you first need to install it. And here's how you can do it.

Step-by-Step Process to Install TypeScript

Step 1: Download and Install the NodeJS Framework

The first step is to download and install the Node.js and NPM version. To install Node.js, you need first to visit the Node download page. We recommend you utilize the LTS (long-time support) version because of its extreme stability.

Step 2: Go to the Start Menu and Click the Command Prompt

After Node and NPM installation, run the below command in the NodeJS command prompt:

npm install –g TypeScript

The command will install TypeScript into your local systems.

Step 3: Verify Your Installation

You can verify if you've installed TS by running the command below.

tsc -v

tsc is a TS compiler, while the -v flag displays your TS version.

Once you confirm this, you can see that TS has been installed successfully. Furthermore, you can also install the specific TypeScript version using the command '@' and accompany it with the version you want.

For instance:

npm install –global TypeScript@5.4.2

How To Install TypeScript into a Current Project?

You can also use TS on a per-project basis. In simple words, you can easily install TypeScript into your current project. This helps you with multiple projects using different TypeScript versions, ensuring each project functions consistently without any interactions with each other.

Hence, to install the TS compiler locally for your project, you can use the below-mentioned command:

npm install –save-dev TypeScript
