TypeScript vs. JavaScript: The Pros and Cons for Web Developers

Many web developers are unsure about which language to choose for their projects – TypeScript or JavaScript? Should the existing JavaScript code be converted, or is it better to develop from scratch with TypeScript? What are the respective strengths and weaknesses of each language?

Recent reports on StackOverflow[1] and Node.js[2] show that there is a sharp increase in the number of developers looking for TypeScript support. The reason for this is simple: TypeScript offers a number of features that JavaScript does not. It may include optional static typing, stricter object-oriented programming, interfaces, classes, and compile-time errors. These elements can help make development easier and more secure.

However, converting existing applications to TypeScript requires a thorough recoding of the existing code. This may involve the use of conversion tools, the new language’s advanced features, and a period of adjustment. Not only that, but implementing types can sometimes lead to undesired abstraction that increases the complexity of the networking code. Rate of development can slow significantly, and debugging time can increase exponentially.

In this article, you will learn about the pros and cons of using TypeScript and JavaScript for web development. We’ll start by looking at the current trends in TypeScript adoption, and the main features it has to offer its users. You’ll also discover the advantages and disadvantages it brings to the table, as well as the implications for developers who make the switch from one language to the other. Finally, you’ll learn how to decide which is best for your project.

Discover the Differences: TypeScript vs. JavaScript

Once upon a time, in an ever-widening world of web development, two programming languages emerged: TypeScript and JavaScript. One had a vision of providing typed interfaces and classes to enhance JavaScript development; the other, an interpreted programming language that helps designers create interactive web sites, web applications, and mobile applications.
They both have made a lasting impression within the community and their strengths and weaknesses have set the stage for some interesting debates among web developers: What are the pros and cons of TypeScript and JavaScript?

Pros of TypeScript

TypeScript offers a number of advantages that JavaScript doesn’t, like:

  • Types. Before TypeScript, JavaScript was a dynamically-typed language with no type checking. With the introduction of TypeScript, developers are able to use static type-checking which helps reduce errors, increases code readability, and allows for type-safe code refactoring.
  • TypeScript Compilation. Since TypeScript is not natively supported by browsers, you need to compile the code into JavaScript for it to run in the browser. This gives developers the opportunity to transpile the code to different versions of JavaScript that can run in browsers, thus providing backward compatibility.
  • Advanced Features. TypeScript supports classes, modules, Lambda functions, as well as many other object-orientated programming (OOP) features—features that aren’t available in JavaScript.
  • IDE Support. Since TypeScript is a superset of JavaScript, it’s easy to find plugins and extensions that support the language in popular IDEs like Visual Studio Code and Atom.
  • Strong Community. TypeScript’s popularity continues to grow, and so does the community supporting it. On Stack Overflow, TypeScript is the 5th most-talked-about language and many users provide helpful tips and advice on how to use it.

Cons of TypeScript

Despite the advantages of TypeScript, there are some snags that can set web developers back. These include:

  • Developer Experience. TypeScript introduces a learning curve for web developers who have only used JavaScript and a static language like Java. These developers can find TypeScript difficult to learn and understand, as the syntax is slightly different.
  • Compilation Time. TypeScript needs to be compiled to JavaScript before it can run on a website or application. This can lead to long compilation times, especially when large chunks of code are involved.
  • Debugging. Without the right tools, debugging TypeScript code can be difficult, as the un-compiled code is almost impossible to read.
  • Limitations. TypeScript only supports ECMAScript 3 (ES3) or later, meaning that certain ES5 features like the iterators and generators are not supported.
  • Browser Support. TypeScript is not supported natively by browsers like Chrome. This means that the code needs to be transpiled into JavaScript in order for it to be executed in the browser.

What is the Difference Between JavaScript and TypeScript?

When it comes to building dynamic websites and applications, developers rely on two of the most popular coding languages – JavaScript and TypeScript. But while both of these languages have their merits, they also have their fair share of quirks that could be a deciding factor for developers.
For starters, it’s important to understand the differences between JavaScript and TypeScript. JavaScript is a scripting language, meaning it can be used to make changes to page content in real time. TypeScript, on the other hand, is a superset of JavaScript, meaning it supports all the features that are included in JavaScript but also adds a few extras. TypeScript provides developers with improved tooling support, static type checking, and access to future JavaScript features.

Prose and Cons to Consider

Which language should developers choose – JavaScript or TypeScript? Although both languages provide their own unique benefits, there are some pros and cons that should be considered when making the decision.
One of the big advantages of JavaScript is its ubiquity. It is the most commonly used language on the web, so the majority of developers are familiar with it. Plus, there are a lot of libraries and frameworks available that are written using JavaScript, which makes it easier for developers to find existing code they can use.
On the other hand, TypeScript provides developers with some significant benefits. The static type checking feature reduces the chances for errors at runtime, and the tooling support can save a lot of time and make coding easier. Additionally, TypeScript supports object-oriented coding, which can make large projects easier to manage.
Yet there are some downsides to TypeScript as well. It takes more time to learn, and it requires an extra step of transpilation to convert TypeScript to JavaScript. Additionally, not all libraries are compatible with TypeScript, so developers can sometimes be stuck with an older version.
So, is TypeScript worth the extra effort? That’s a question developers will have to decide for themselves. But when it comes to leveraging modern features such as static type checking and object-oriented programming, TypeScript can be a real benefit. All in all, TypeScript provides developers with improved features and easier maintenance – making it potentially worthwhile to switch from JavaScript.
