What is TypeScript?
If you are a C# or Java developer, typescript will be nothing more than another “Hello Word” program for you.
So, Typescript comes into the picture. This makes writing the code easier by using powerful features like interfaces, inheritance, and classes and dedicated datatypes for easy readability and fast passing of the development.
Is TypeScript Open Source?
If you wanted to contribute to the typescript project. All you need to do is just make changes and raise PR with the and if it gets approved. Then you become one of the contributors to typescript language.
Documentation and Community for TypeScript
It has a huge community where you can always ask for help and higher chances of getting a response in no time.
- Copy some code from StackOverflow
- Chat with the online users on Discord
- Follow the trending tweets about TypeScript on Twitter
- Pass feedback on Github
How to install TypeScript
For the latest stable version:
npm install -g typescript
For our nightly builds:
npm install -g [email protected]
When to use TypeScript?
Catch Issues at Compile Time
Since TypeScript is a strongly typed language, it can detect a much wider range of issues in your IDE. You don’t have to wait until you run the program and use numerous console log statements to log the issue.
Refactoring the Code
When you have written a good amount of code and trying to refactor the legacy code written by someone else. The chances of introducing bugs are very high. When you refactor, TypeScript not only assures you that nothing was missed but also identifies the areas that need updating. You no longer need to manually track your variables all over the code.
Unexpected autocomplete in TypeScript has emerged as one of the main factors contributing to its popularity.
Autocomplete means I don’t have to worry about typos (did we name this prop
colour?). I don’t have to keep jumping between files to see which component props I need.
Use TypeScript with VsCode IDE to utilize the most out of it. Because both are developed by Microsoft and have great integration.
- Interoperability – It perfectly aligns with other languages. You can easily embed JS into a webpage or inside the script of a particular programming language.
- Server Load – JS operates on the client side. This means you can validate the data on the browser itself instead of sending it off the server.
- Rich Interfaces – It offers multiple interfaces to help developers create intuitive web pages.
- Extensibility – JS allows developers to add snippets of predefined code within the code with the help of third-party integrations.
- Versatility – You can use it for the frontend (by utilizing libraries like Angular, React, etc.) and backend (by utilizing Node JS) requirements.
- Security – As JS code is viewable to the user, it is subjected to malicious intent or can result in data malfunction.
- Debugging Facility – Indeed, some HTML editors support debugging but are not as efficient as C/ C++ editors.
- Single Inheritance – It is unable to provide support for multiple inheritances.
