Odd 7 differences between Javascript & Typescript

JavaScript & TypeScript are both popular programming languages, but they have some key differences that make them suitable for different use cases.

JavaScript is a dynamic, interpreted language that was first created in 1995. It’s the most widely-used programming language on the web and is supported by all major web browsers. JavaScript is often used to create interactive front-end web applications and is also used in back-end development through technologies such as Node.js. JavaScript is a versatile language that can be used for a wide range of tasks, from simple scripts to complex web applications.

TypeScript, on the other hand, is a relatively new programming language that was first released in 2012. TypeScript is a superset of JavaScript, which means that any valid JavaScript code is also valid TypeScript code. However, TypeScript adds additional features such as static typing and classes, which make it more suitable for large-scale applications. TypeScript is often used in conjunction with JavaScript for building enterprise-level applications and is gaining popularity in the web development community.

Main differences between JavaScript & TypeScript

One of the main differences between JavaScript & TypeScript is the type system. JavaScript is a dynamically typed language, which means that the type of a variable can change at runtime. This can make it difficult to catch errors early on in the development process. TypeScript, on the other hand, is a statically typed language, which means that the type of a variable must be specified at the time of declaration. This makes it easier to catch errors and makes the code more predictable.

Another key difference between JavaScript & TypeScript is the class system. JavaScript has a prototype-based class system, which can be a bit tricky to work with. TypeScript, on the other hand, has a class-based system that is more similar to traditional object-oriented programming languages such as Java and C#. This makes it easier to work with large-scale applications and to create reusable code.

TypeScript also has better support for interfaces, which are used to define the structure of an object. Interfaces in TypeScript provide a way to define the shape of an object and ensure that it has certain properties and methods. This makes it easier to catch errors and makes the code more predictable. TypeScript also provides a way to define the types of function arguments and return values, which can help to catch errors early on in the development process.

Another advantage of TypeScript is its ability to catch errors early in the development process. TypeScript’s type system can help developers to find errors before they are deployed to production, making it easier to maintain and update the code. TypeScript also provides better tooling support than JavaScript, which can make development faster and more efficient.

In terms of performance, there is no difference between JavaScript and TypeScript, since TypeScript code is transpiled to JavaScript during the build process. However, TypeScript’s additional features and better tooling support can make development faster and more efficient, leading to better performance in the long run.

In summary, while JavaScript is a versatile and widely used language that is suitable for a wide range of tasks, TypeScript is a more powerful and efficient option for large-scale enterprise applications. TypeScript’s static typing and class-based system make it more suitable for creating reusable code and catching errors early in the development process. Additionally, TypeScript’s interfaces and better tooling support can make development faster and more efficient.
