6 Pros and Cons of TypeScript over JavaScript – 2024 Beginners Guide

TypeScript is a relatively new open-source programming. It was first introduced in 2012, and ever since then, it has been climbing on the ladder of most commonly used languages. Now, in 2024, it is extremely close to JavaScript that has been holding the number one spot for front-end development. Beginners in programming languages are wondering if investing their time in learning TS is going to be worth it in the long run.

In this guide, we are going to tell you more about the pros and cons that come with TS, so you can make the right choice when it comes to upgrading your personal skills, choosing the right company or deciding which type of programming is better for your website or your software.


Let’s look at the positives TypeScript has, and when you should choose it before you decide to try your luck with JavaScript.

1. Exact commands

The first thing that is a huge pro when it comes to this programming language is that you can give it exact commands when you are creating the software. It is going to be easier for you and for your team to express what you want when you use TS, and it is going to be easier for the developers to make that happen.

When you are developing something for a client, they usually have an envision of what they like their website to be. When using TypeScript, you, as a company, will be able to incorporate the needed design with ease using types, abstract classes, and interfaces.

All of these things are making this open-source programming language really predictable, and this means that when you want the function to do something, it will do it. There won’t be the element of surprise and you won’t get any additional bugs that should not happen or appear.

2. It is based on OOP

This type of development is based on object-oriented programming and it uses a lot of similar features. This means that the whole code is very well organized, and it can be read with ease.

Most back-end developers are more comfortable with using OOP when writing their code and TS, compared to JavaScript, is a lot easier to understand. This means that several programmers can work on the same code, and they won’t have an issue with continuing where their coworker left off.

Another positive thing about this is that TS is made to catch bugs and the statistic shows that it can recognize errors and catch bugs at the earliest stages. It is said that it can recognize about 20 percent of the most common bugs even in the compile stage.

3. Wide use and application

One thing that you may be worried about is the use of TypeScript. Lately, more and more software is made with this programming language and it is also used in popular frameworks.

Even though most of the things we know and use were based on JavaScript, experts say that TS is taking over. The reason why TS is used so much is that it can be used everywhere and we suggest you to click on this link to get more details about that. On the other hand, JS can only be used for front-end development, but not for the backend.

In other words, if you are looking for a programming language that can be used to develop both the interface and all the features, including the smallest details, you should choose TS.


Even though TypeScript is amazing when it comes to so many things and applications, there are also some negatives to this programming language. Let’s look at the things that you should know before you decide the right path for you.

1. You have to spend a lot of time learning it

There is a big learning curve when it comes to TS and it is harder for you to find a person who has all the needed skills. JS focuses only on the frontend development, and with that, it is easier to understand and the codes are easier to write.

TS is a lot more complex and it requires greater knowledge. You will be able to find JS developers with ease, and you should know that most of them cannot code in TS.

2. It is difficult to edit

One of the main things we look into a programming language is the ease of editing and upgrade. For example, functional programming lets us edit the code when needed, no matter how many changes we want to make to it.

TS is hard to change and edit, especially if you are using CMS to build your website. This means that when you have to make some needed changes, or if you notice that there is a mistake that needs to be corrected, this could take a lot of time, and with that, a lot of money.

3. You need to convert it before use

Because this programming language is relatively new, it is not commonly used in most browsers. This means that platforms are not made to interpret the code. Because of this, you will have to translate it to JS if you want everything to work without any issues.

One of the main problems with the conversion is that there could appear additional bugs, and you may have to spend some extra time fixing those errors. However, there is a positive as well. You don’t have to translate it manually and you can use automation so that everything can be done fast and with ease.

These are the most important things you should know about TypeScript and how it wages when compared to JavaScript. As you can see, both languages have their positive and negative sides. When choosing the right company or person to develop the software for you should talk to them about the ability to use any of these languages.

You should also consult with them and see how they can help you develop a faster, better, and a program that is user-friendly.
