TypeScript is a programming language that can be used to create robust, well-organized code. It’s popular among developers for its clear syntax and ability to communicate type information to other developers. However, TypeScript is reliant on JavaScript, so can you learn it without learning JavaScript first?

You can learn TypeScript without JavaScript. However, it’s much easier to learn it if you already know JavaScript as you work through its fundamentals and syntax. You should learn TypeScript because it’s a great choice to help you build better applications, and it’s gaining popularity.

This article will discuss whether you should learn TypeScript without learning JavaScript and if it’s worth the time investment. We’ll also discuss what difficulties you might run into when trying to switch your career to TypeScript.

What Is TypeScript?

TypeScript is a programming language developed and maintained by Microsoft. It is free and open-source, with support available through Node Package Manager, NPM, and Visual Studio Code’s built-in support.

TypeScript adds optional static typing to JavaScript, allowing developers to detect errors in their code using IDEs like Visual Studio Code. These IDEs can offer code completions based on variable types and syntactic sugar for declaring variables.

The tools are intended to ease development for large teams of developers. TypeScript does not change how browsers work or how applications are deployed; it simply defines some new syntax rules that give us additional capabilities we didn’t have before.

Is It Possible To Learn TypeScript Without Knowing JavaScript?

It’s possible to learn TypeScript without knowing JavaScript, but it’s much easier if you already know JavaScript. The two languages share certain syntax elements like function and class.

However, unlike Ruby or Python, where you can get by knowing just one language, it is very hard to learn TypeScript without knowing JavaScript first. Read on for a more thorough explanation.

Why You Should Learn JavaScript before TypeScript

The obvious reason is that it’s impossible to understand TypeScript without understanding its “parent” language, JavaScript. Understanding what type of code TypeScript generates would only make sense after learning JavaScript.

Additionally, not knowing JavaScript will severely limit your ability to understand more complex TypeScript features like decorators or asynchronous programming. In short, if you’re serious about learning TypeScript, then learn JavaScript first and start with basic concepts like data types and functions/methods before going into classes/modules.

TypeScript is a superset of JavaScript. This means that all the same features and syntax are present in TypeScript files and many others. Because of this, learning TypeScript can help you become more familiar with JavaScript and its syntax.

As you know now, both coding languages are similar in many ways. Therefore, when you switch from JavaScript to TypeScript or vice versa, your code may look weird at first, but with some practice, it should still work.

The Benefits of Learning TypeScript

TypeScript is a popular language among developers and has been used in many high-profile projects such as AngularJS and React.js. Therefore, if you want to be a well-rounded developer, learning TypeScript would be a good idea.

TypeScript has many benefits over JavaScript, including strong typing, type inference, and modularity.

TypeScript can be used standalone or in conjunction with JavaScript.

While learning TypeScript may be difficult without prior experience with JavaScript, the benefits of learning TypeScript are worth the effort.

TypeScript has many benefits, including:

  • TypeScript code is easier to maintain, debug and update than pure JavaScript code since the compiler will catch any possible errors at compilation time instead of runtime.
  • It also offers improved IDE support and the ability to use more powerful features like generics, interfaces, and type assertions which isn’t possible with pure JavaScript.
  • TypeScript can also help you write more readable code by providing type inference and string interpolation features.
  • TypeScript can help you write more maintainable code by providing features like modules and classes.

Which Is Better To Learn: TypeScript or JavaScript?

Both TypeScript and JavaScript are useful languages, but you should learn JavaScript first. This will make it easier to learn TypeScript down the line.Ultimately, both are powerful and popular languages; it will be worth your while to explore both fully at some point.

If you’re learning for a job, your employer may require that you learn TypeScript. If you’re doing it out of interest, consider whether you have the time to dig into another language right now.

The fact that they share much of their syntax will only make switching between them more manageable as well. You can learn TypeScript without learning JavaScript, but you will likely find it harder to get started and be less productive. If you want to use TypeScript in your web applications, it is best to learn both languages, but you should probably start with JavaScript first to make things easier.

Is TypeScript Easier To Learn Than JavaScript?

While it’s hard to argue that using TypeScript isn’t easier than writing plain JavaScript, much of what makes it easier is, in fact, due to the first-class knowledge of JavaScript. If you are an experienced developer with JS under your belt already, you’ll have no problem picking up TypeScript.

On top of that, most developers take their time when learning a new language anyway. So, for someone who can grasp concepts like variable scoping and loops and conditional statements, then jumping into TypeScript won’t be too far out of reach.

While it’s true that you can’t learn and understand TypeScript without having a solid understanding of JavaScript, going into it blind might be more complicated than it’s worth. This is especially true if you aren’t already familiar with object-oriented programming or any other type of coding language.

Learning multiple languages at once can make things even more confusing, so take your time and consider whether you want to go through learning both JavaScript and TypeScript. That said, if you do decide to go for it, there are many online tutorials available to help clear up some of that confusion; just make sure you’re choosing from high-quality ones that explain each concept thoroughly before moving on to the next.

TypeScript shouldn’t be too hard to pick up if you’re already comfortable with JavaScript. However, there are some definite advantages to learning TypeScript first.

For instance, TypeScript has more robust type checking and error detection features than JavaScript. Your code will compile much more seamlessly, and errors will be caught earlier, which is especially valuable when working with larger projects.

Additionally, because TypeScript is a superset of JavaScript, you can take advantage of all the existing libraries and tools compatible with JavaScript. This makes transitioning from one to the other relatively easy. Finally, since TypeScript is a language created by Microsoft, it enjoys significant support from the company behind JavaScript, making it a more reliable and bug-free option than some other languages.

So if you’re looking for an easier way to get started in programming or want to work with a more reliable language, TypeScript may be the answer for you.

Should I Switch From JavaScript to TypeScript?

Switching to TypeScript will boost your development skills and make your code more reliable. So should you switch from JavaScript to TypeScript? If you are looking for a more robust language that will help improve your development skills, then yes, definitely switch!

TypeScript has features that make it easier to work with large teams and projects. It also has features that make it easier to write type-safe code, which can help you avoid many of the mistakes you might otherwise make in JavaScript.

If you are already familiar with JavaScript and want to learn a language that will help you avoid the most common mistakes and will allow you to handle large projects more efficiently, then TypeScript might be a good choice for your next language.

TypeScript is more powerful and versatile than plain old JavaScript. For example, you can use type annotations to tell the compiler which types of variables and functions should be treated as strings or numbers, respectively. Additionally, TypeScript has its own built-in types like records and classes.

However, without experience with JavaScript, it may be difficult to understand how TypeScript works. Furthermore, since TypeScript is a superset of JavaScript, certain features of JavaScript (like closures) are also available in TypeScript. This may cause confusion for beginners who are unfamiliar with these concepts.

Ultimately, whether or not you should switch from JavaScript to TypeScript depends on your skills and preferences. If you’re confident that you can understand both languages well enough, then go ahead and learn TypeScript!

Will TypeScript Replace JavaScript?

TypeScript has some features that make it more powerful than JavaScript, but it’s less popular. It’s unlikely that TypeScript will replace JavaScript anytime soon, as the two languages are complementary. JavaScript is used for scripting tasks and TypeScript for high-quality, type-safe code.

TypeScript supports a wide range of features that make it a powerful tool, such as interfaces, generics, and class inheritance. Additionally, it can be used in conjunction with various other languages such as Node.js and React.js. Some developers have commented that they believe it will be used more as a tool for debugging or writing unit tests than for actual production code.

Is It Worth Switching to TypeScript from JavaScript?

In general, it’s worth switching to TypeScript from JavaScript because it’s a great language for creating type-safe code and it’s easier to learn. On the other hand, JavaScript can be more useful to learn as it’s more comprehensive.

There are pros and cons to learning TypeScript. The pros are that it makes your code more type-safe and readable. And if you’re uncomfortable with JavaScript, you may find it easier if you transition to TypeScript. Once you’re comfortable with TypeScript, switching to JavaScript should be much easier.

However, it can take a while before you start to see the benefits of using TypeScript. If you’re unsure whether it’s worth switching to the language from what you use now, it may be best to wait until you see some real benefits.

It’s tempting to ask, whether you should learn TypeScript. However, it might be better to ask whether you should try out TypeScript. If your work involves web development, then odds are good that you could benefit from using TypeScript.


TypeScript is a superset of JavaScript and provides many benefits (including improved type safety) that make it an excellent choice for larger projects. If you’re confident in your ability to understand and use TypeScript concepts, then, by all means, go ahead and start using it without any prior experience with JavaScript.

However, if you’re not quite ready to jump into full-blown TypeScript development just yet, I recommend starting with some smaller projects to get a feel for the language before embarking on something more ambitious.
