Features of TypeScript:
- Use TypeScript anywhere: TypeScript code can be run on any browser, devices or in any operating system. TypeScript is not specific to any Virtual-machine etc.
Generally TypeScript takes time to compile the code.
- Before outlining the differences between both, let us understand what each language looks like!
- Flexible, dynamic and cross-platform
- used for both client-side and server-side
- Lightweight interpreted
- Supported by all browsers
- Weakly typed
- JIT compilation
If you observe, the syntax of the functions is similar to Java, however, we have defined the variables as ‘var’ and not declared them as any type. The myFunction() function is triggered when the user clicks on a ‘Submit’ button and gives appropriate alert messages as per the conditions. Here is sample output –
As we see above, TypeScript is strongly typed. This makes it better to debug (during compile time itself) which is a more efficient way to code for large projects. TypeScript programs typically consist of modules, functions, variables, comments, expressions, and statements – just like any other full-fledged programming language. Some prominent features of TypeScript are –
- Easy to maintain and enhances project productivity
- Static typing and annotations are possible
- Supports object-oriented features like interface, inheritance, and classes
- Easy to debug and early detection of errors
- Supports ES6 (ECMAScript) that offers easier syntax to handle objects and inheritance features
- The good full-fledged IDE support
- Instructor-led Sessions
- Real-life Case Studies
When should you migrate your project to TypeScript?
When the code becomes huge, complex to handle, and more prone to errors, it is better if some errors are caught during compile time itself. That is where TypeScript helps. The beauty is that the entire codebase written in Java can be reused as such.
Now as we understand the basic features and purpose of both, let us explore some more low-level differences apart from what we have already learned so far –
|Errors can be found and corrected during compile time||Errors can be found only during run-time as it is an interpreted language|
|Strongly typed, supports both static and dynamic typing||Weakly typed, no option for static typing|
|There is support for ES3, ES4, ES5 and ES6 Supports modules, generics and interfaces to define data||No support for compiling additional ES3, ES4, ES5 or ES6 features|
|Functions can have optional parameters||No support for modules, generics or interface|
|Powerful and intuitive language||Neat and clean, most suitable for simple web applications|
|The community support is still growing and not so huge||Huge community support with lots of documentation and support for solving issues|
|Prototyping is possible Takes time to learn and code, scripting knowledge is a must.||Prototyping support is not there Can be learned on the go, no prior scripting experience is needed.|
|Proper build setup (npm package) is required for static type definitions||No build setup is required|
