TypeScript vs JavaScript 2023: Which Is Better?
The software industry has come a long way since its very inception. Today, it is one of those sectors that are a hub of digital transformations; one that best encourages technology to test new waters and provide businesses/clients with innovative solutions.
What we sometimes fall short of understanding is that behind every successful innovation, there is a web of techniques and tools, leveraged by the experts of the industry to best serve us. When it comes to software development, it takes a bunch of complex codes and tool combinations to bring the kind of ease that today’s business requires. It is through these well-built programming languages that they can streamline, automate or digitize their internal processes – all to eventually embrace growth at a faster pace.
Developers who are fairly new to the realm of software application development often find themselves lost in the maze of diverse tools. For each solution, there are plenty of options for them to explore and experiment; so much so that they sometimes end up confusing two teams for each other; for example, the all-popular dilemma of TypeScript vs. JavaScript. Many developers struggle to decide on which one is better when it comes to TypeScript vs JavaScript performance.
Let’s take a closer look at what TypeScript and JavaScript mean, along with their features. Then, we will move on to discovering the key differences between TypeScript and JavaScript to help developers determine which one is better.
What Is JavaScript?
JavaScript (abbreviation: JS) is a scripting language for the web that holds the power to update and change both HTML and CSS. Being the smarter one of all the programming languages, it can effectively and efficiently inspect, manipulate and validate data. Want to incorporate complex features throughout the website? JavaScript is the programming language you turn to.
It is the ultimate tool to add a dynamic touch to a website. The most common use of JavaScript is to dynamically modify HTML and CSS to update content, animate images, illustrations, or other graphics, create interactive maps, menus, video players. HTML and CSS on their own can create a functional website but it’s with JavaScript that you can make it exceptional. Few simple Java codes sprinkled here and there can actively make a web page look more inviting and; such is the magic of JavaScript! It is crucial when it comes to an excellent user experience.
Features Of JavaScript
1. Platform Independent Programming Language:
Given that JavaScript is an interpreted language, it is naturally compatible with diverse browsers like Windows, Macintosh, and other Netscape-supported systems as well. In addition, developers can also integrate it into other scripts like HTML. JavaScript is not entirely dependent on web servers. Hence, it can provide excellent control to the browser, eventually contributing to a significant reduction in server load and network traffic.
2. Dynamic HTML Content Generation:
If a project requires the generation of HTML content dynamically, then look no further than JavaScript. The programming language comes with impressive features that best take care of this task. It brilliantly enables developers to add text, links, images, tables, and such, even after an event occurs.
3. Quick User Input Validation:
User input validation is primarily known as form validation. This feature allows users to fill different forms provided on web pages, and thus, engage with the client. When users fill in their accurate details into the form fields, it becomes easier for the client to validate this user information and provide them with a better website experience.
What Is TypeScript?
There’s a fascinating history surrounding the origin of TypeScript. JavaScript was first designed as a client-side programming language. Over time, developers took notice of the fact that it could be leveraged as a server-side programming language as well. As JavaScript flourished, it started accommodating heavier codes. This became a challenge as the programming language could no longer best serve the role of an object-oriented programming language, meaning that it could not cater to enterprise-level requirements. This is what led to the creation of TypeScript – the ultimate tool capable of bridging this gap.
Designed by Anders Hejlsberg (designer of C#) at Microsoft, TypeScript is essentially JavaScript for application-scale development. It is a more evolved kind of JavaScript development language that features a refined set of tools. When working on a large-scale JavaScript project, it is best to consider TypeScript. It can help developers bring in more efficiency in the form of easily deployable codes.
Will TypeScript replace JavaScript? The possibility is slim as TypeScript is a tool built to complement JavaScript. The main objective of TypeScript is to write clear and simple JavaScript code. Is TypeScript worth it? Absolutely yes. It is a powerful statically typed, object-oriented language. The simplest way to describe TypeScript would be – a tool that mirrors JavaScript but is topped with some additional features.
Features Of TypeScript
1. Superset Of JavaScript:
In its truest sense, TypeScript is a complementary language designed for JavaScript. It is built on the back of JavaScript to ensure robust software development for large-scale projects. All of the code written in TypeScript can be eventually converted into its JavaScript version for quicker deployment and execution. Any valid .js file can be renamed to .ts. The JS file can be easily integrated with other TypeScript files.
2. Library Support:
The best part about TypeScript is that it supports other JS libraries. All of the existing JavaScript tools, libraries, and frameworks can be leveraged while building programs first on TypeScript. This program can then be translated into JavaScript with much ease.
3. Easy Portability:
TypeScript makes for hassle-free portability across multiple devices, browsers, as well as operating systems. The tool does not require a dedicated VM or a specific runtime environment to execute. It can run on any platform and environment that JavaScript runs on.
TypeScript vs JavaScript: Key Differences
| TypeScript | JavaScript |
| Typescript is a superset of JavaScript, designed to build simpler codes. | JavaScript is a scripting language designed to help developers create interactive web pages. |
| Key features: powerful type system, including generics & JS features. | Key features: lightweight, object-oriented language with first-class functions. |
| With TypeScript, one can statically type multiple JavaScript features like union types, intersection, discriminated union. | JavaScript offers the option to explore and create code without a build step. |
| Typescript code needs to be compiled. | JavaScript code doesn’t need to be compiled. |
| To describe the data being used, TypeScript uses concepts like types and interfaces. | The concepts of this kind are not used when working with JavaScript. |
| Typescript supports the prototyping feature. | JavaScript doesn’t support prototyping. |
| To make the most out of TypeScript features, developers are required to constantly annotate their code. | With JavaScript, developers do not have to deal with annotations. |
| As it includes generics & JS features as well, Typescript is the best bet for large projects. | JavaScript has proven to be a go-to solution for small-scale development projects. |
| To master TypeScript, one has to have prior scripting experience. | This programming language is flexible and is easy to learn for beginners as well. |
| TypeScript falls a little short in terms of community support. | JavaScript has a huge community of expert developers. |
