What is TypeScript?
If you come from an object-oriented language like C# or Java, you’ll find many familiar features on the list that TypeScript adds. My favorite ones include enums, interfaces, access modifiers, namespaces, generics, and many more.
TypeScript is great for large scale web applications, as you can write frontend and backend code with it. On the backend, you need to install a library called ts-node To execute TypeScript code in a Node.js environment.
In 2022, TypeScript joined the world of Top 5 most used languages, This isn’t surprising, as TypeScript is constantly evolving, adding new features, and has a great developer community that the TypeScript team listens to.
When used in pairs with newer IDEs such as Visual Studio Code, TypeScript offers great Intellisense features such as code hinting and code completion. Those features help increase the pace of program development.
In addition, TypeScript allows the use of some ES6 and ES7 candidate features that are not yet supported by the major browsers. For example, the optional chaining operator and class constant They were available in TypeScript long before ECMAScript officially supported them.
Although TypeScript offers many advantages, it also brings some disadvantages. None of those pitfalls are deal-breakers, but a new developer should be aware of them and consider them.
Another disadvantage of TypeScript is the additional compilation steps required. This step can slow down build times and complicate bundler setup.
Since TypeScript adds many new features that may be unknown to a frontend developer, it increases the learning curve of a codebase. In fact, when used to its full potential, it can be challenging for untrained developers to understand TypeScript and requires a lot of googling or advice from older peers.
Finally, some developers complain that using TypeScript requires adding a lot of extra code to define types. While true, it saves time in the long run because it’s easier to onboard new project members. It also makes refactoring of the codebase easier.
When should you use TypeScript for a new project?
Adopting a new technology that you have no experience working with can be difficult. However, with TypeScript, it’s worth a shot, as its advantages outweigh its disadvantages.
If you work on a project with teammates, the decision is more complicated, as it requires the consent of the team and management. Although, ultimately, using TypeScript will help your team, it will slow down development in the short term. Also, the team needs to be prepared to spend some time learning TypeScript, its features, and its best practices. This is where having an experienced teammate with TypeScript or another object-oriented programming language (such as C#) will help the team make a smooth transition.
If your team is willing to sacrifice short-term performance loss and initialization time to learn TypeScript, I recommend using TypeScript in your project. you will not regret it.
When should you not use TypeScript for a new project?
Even though TypeScript is generally great, there are reasons I wouldn’t recommend using it.
The biggest reason not to use TypeScript is if you or your team has to respect a strict deadline. The deadline is quite stressful, and it is not recommended to add a new technology that you have no experience working with. Unfortunately, learning TypeScript takes time, and this time may be better spent elsewhere for projects with deadlines.
In addition, configuring TypeScript can be challenging, especially for beginners. This may require installing multiple npm libraries and working with a bundler (such as webpack). If you’re not ready to spend the time learning this new information, don’t use it.
Another thing to consider is that using TypeScript will increase the entry limit for developers. If the project is open-source, this may increase the difficulty of developers contributing to it.
Also, for managers and hiring personnel, using TypeScript in a project means that the developers you hire must have experience using TypeScript or another. Oop Language: Hindi. Adopting TypeScript increases the minimum job qualification to work on the project and can increase the budget of the project, as you need to hire more experienced developers.

Another option is to keep legacy code and just write new features in TypeScript. When a feature touches a piece of legacy code, you can migrate as you work on it.
Even though it has some disadvantages, such as the code complexity that it adds or the extra compile time, it will save you time in the long run.
If you work alone, I strongly encourage you to build your next application using TypeScript.
If you work with a team, adopting TypeScript may require some convincing. I encourage you to start building a TypeScript project in your spare time. Then you can show it to your peers and tell about all the benefits of TypeScript.
