TypeScript vs Dart – Key Differences

Two popular programming languages for frontend development are TypeScript and Dart. While they have some similarities, they also have striking differences that set them apart.

TypeScript is a superset of JavaScript, which means it adds more features to the language and can easily integrate with existing JavaScript code. It also has a strong typing system that can catch errors before runtime.

On the other hand, Dart is a standalone language designed by Google for web and app development. It has a more concise syntax and supports both just-in-time and ahead-of-time compilation, making it a versatile language for different environments.

Language Features

TypeScript, which is a JavaScript superset, adds optional static typing and class-based object-oriented programming to the language. This makes it ideal for developing large-scale applications that can be used for server-side and client-side development.

On the other hand, Dart is an object-oriented language resembling C, but with some specific features that make it an excellent choice for app development. It supports interfaces, mixins, abstract classes, reified generics, and optional typing. With Dart, you can compile your code to either native code or JavaScript, making it versatile and well-suited for modern app development.

Syntax Comparison

TypeScript’s syntax is similar to that of JavaScript, which makes it easier for developers who are already familiar with JavaScript to learn. On the other hand, Dart has its own unique syntax that is easier to read and write.

Let’s compare the syntax of TypeScript and Dart in some common programming scenarios:

Defining Variables:

  • TypeScript:

let x: number = 10;
const y: string = 'Hello World';

  • Dart:

var x = 10;
const y = 'Hello World';

Defining Functions:

  • TypeScript:

function greet(name: string): string {
return `Hello, ${name}`;

  • Dart:

String greet(String name) {
return 'Hello, $name';

Defining Classes:

  • TypeScript:

class Animal {
name: string;

constructor(name: string) { = name;

move(distanceInMeters: number) {
console.log(`${} moved ${distanceInMeters}m.`);

  • Dart:

class Animal {
String name;


void move(int distanceInMeters) {
print('$name moved ${distanceInMeters}m.');

Defining Interfaces:

  • TypeScript:

interface Printable {
print(): void;

  • Dart:

abstract class Printable {
void print();


  • TypeScript:

function identity<T>(arg: T): T {
return arg;

  • Dart:

T identity<T>(T arg) {
return arg;

From these examples, you can see that TypeScript and Dart share a similar C-style syntax. The main differences arise from TypeScript’s type annotation syntax, which is similar to other statically-typed languages like C# or Java. Dart syntax is more concise in certain scenarios (e.g., constructor syntax), which is part of its aim to be a more streamlined and easy-to-learn language.


TypeScript is ideal for developers who are building large-scale web applications and want to add static typing to their JavaScript codebase. This helps reduce the number of bugs and makes the project more manageable.

On the other hand, Dart was developed by Google and is heavily used within Google’s own Flutter framework for building cross-platform mobile apps. However, it’s also a suitable choice for web and server applications.

Community and Support

Being built upon the ever-growing JavaScript community, TypeScript has become a go-to language for many developers due to the pre-existing abundance of libraries and support.

However, that doesn’t mean Dart is lagging behind. With the increasing popularity of Flutter, Google’s open-source app development framework, the growth of the Dart community is no longer a matter of if, but rather when. Furthermore, Dart enjoys unfaltering support from Google itself, giving it a solid foundation to continue growing in the years to come.

Learning Curve

For those already familiar with JavaScript, TypeScript may come more intuitively as it’s essentially just JavaScript with a few added features. However, it may pose a challenge for those who are not as accustomed to managing static types.

As for Dart, its syntax is easy to understand for those who have a background in C-style languages. Although it was designed to be easy to learn, those who are more accustomed to JavaScript may need to take a little extra time getting used to its features and paradigms.


TypeScript is known for its strong support in many IDEs and text editors, while Dart’s tooling is particularly strong in IntelliJ IDEA and VS Code with a Dart plugin. TypeScript has robust auto-completion thanks to its static typing, making debugging a breeze.

Dart also has much to offer, including a standalone SDK that includes a VM, libraries, and command-line compiler.


TypeScript relies on the JavaScript engine to execute code, which means that performance may vary depending on the engine’s capability.

On the other hand, Dart has a unique approach to performance. Its code can be Just in Time (JIT) compiled for rapid development and debugging, or Ahead of Time (AOT) compiled for a speedy startup and consistent performance in production.

This means that in some cases, Dart may have an advantage over TypeScript in terms of optimized performance. So, when choosing between the two, it’s important to consider how you want your code to perform.


TypeScript has a clear advantage in this area, thanks to its status as a superset of JavaScript. This means it boasts seamless interoperability with existing JavaScript code and libraries, making it an excellent choice for projects built on top of an existing JavaScript codebase.

On the other hand, Dart can also offer some degree of interoperability with JavaScript, but it’s not quite as straightforward as TypeScript. This is because Dart is a distinct programming language that requires a more deliberate approach to integrating with JavaScript.

TypeScript vs Dart Salary

According to data from Glassdoor, the average salary for a TypeScript Developer is $70,424 per year, slightly more than the average salary for a Dart Developer at $69,977 per year.

However, data from ZipRecruiter tells a different story. The average salary for a TypeScript Developer on this site is a whopping $122,000 per year, while the average salary for a Dart Developer is $95,900 per year.

Whether you choose to work with TypeScript or Dart, it’s clear that both languages have the potential to offer a comfortable salary for developers.

Dart and TypeScript Uses and Applications

Dart and TypeScript are two highly versatile programming languages that can be used in a wide range of applications. While Dart’s optimized code works well on the client side, it can also be used for command-line apps and IoT projects. This is thanks to its multi-platform characteristic, which allows it to compile code for different platforms.

On the other hand, TypeScript’s extra features make it a popular choice for a range of applications, from building servers to game development and smartwatch apps. And since TypeScript is a version of JavaScript, it can be used in any environment where JavaScript is used.

So whether you’re building enterprise-level applications or fun and engaging games, there are plenty of ways to make use of Dart and TypeScript.
