Statically typed languages. Thus, developers need to define the type of each variable, function parameter, and return value in advance.
Let developers organize their code better by introducing features such as features interfaces, classes, and modules
|No built-in support for these features.|
Checks the code at compile time. this is helpful to detect errors before the code is run.
|No such step.|
TypeScript provides more information about variables, functions, and other program elements via its type system to the IDE. consequently, The IDE can do a better job at code compilation, error checking, and refactoring.
Suited for large-scale projects maintainability and code quality are critical in these projects.
Use in smaller projects or for adding interactivity to web pages.
Benefits and drawbacks of using TypeScript
- Early detection of errors
As mentioned before, the TypeScript type systems allow developers to catch errors at compile time.
- Better code maintainability and organization.
This is an essential part of a large-scale project. Interfaces. Classes and modules allow developers to add more organized and easy-to-understand code.
- Better tooling support
- Improve collaboration within the development team.
The TypeScript type system makes it easy for one developer to understand the code written by another developer. This is useful in large-scale projects to minimize misunderstandings and conflict, and thereby to have a clear understanding of the parts of code a certain developer works on.
- Maintainability and scalability
TypeScript promotes maintainable code with less complexity. Consequently, it brings another benefit, which is scalability. Developers can add new code easily for new features for new or changed user requirements over time.
- Steep learning curve
- Additional development time
- Additional tooling required
- Not suitable for all projects
TypeScript may not be suitable for every project. As I mentioned before, it is used in large-scale projects that require code maintainability, team collaboration, and scalability. for small projects, using TypeScript could be an extra burden and work.
- Increased file size
Setting up a TypeScript development environment
There are 3 ways to set up a TypeScript development environment
How to install TypeScript locally( as a Dependency )
- As an npm module if you are using Node.js
npm install typescript --save-dev
yarn add typescript --dev

- Using the NuGet package if you are using MSBuild
- You can also add TypeScript as a Visual Studio extension
How to install TypeScript globally
run npm install -g typescript
This will install the latest TypeScript version in your system.
via Visual Studio Marketplace
If you install TypeScript as a Visual Studio extension, It allows you to use TypeScript across many MSBuild projects in Visual Studio. The latest version is available in the Visual Studio Marketplace.
