What are the differences between the two?
To begin with, TS is majorly used when JS becomes complicated. Where JS stops, TS comes into the picture and saves the day. In short, TS is used for heavy, more complex coding where JS can get challenging to use.
Some important differences between the two are:
- TypeScript uses the principles of object-oriented programming (OOP), which involves the use of classes, interfaces, modifiers and more. It is a multiparadigm language. JS does not have class-based object-oriented programming because it is mostly a prototype-based object-oriented programming language.
- Static typing is seen in TS as it demands a variable type be explicitly declared and determined at compile time. This is not available in JS.
- As mentioned before, TS is used for complex parts and JS is used to solve the simpler parts of a web program.
- TS was developed at Microsoft by Anders Hejlsberg and JS was developed at Netscape by Brendan Eich.
- A JS code can be used for running on any browser but that is not possible in the case of a TS code.
- Compilation takes time in TS whereas a JS code is instantly compiled.
How can I learn TypeScript?
There are a plethora of online courses and free tutorials to choose from. You can easily find the suitable one.
Also, TS is booming in the programming world. A TS programmer is earning around $ 150,000 a year, more than a JS programmer. So, there is a lot of potential in this area. Getting your grip on both JS and TS can actually be a game changer.
TS has been evolving with time and the best part is that it delivers better code. It has improved when it comes to compilation and we have heard from programmers that their experience with it has been extremely smooth. The quality of the code is also good as it is easier to read. One can compile the code efficiently without any hassle. Since it follows multiparadigm principles, it makes it apt for object-oriented programming. One can code using inheritance, classes, with additional features in it, and modifiers.
So, get down and get busy with learning. Happy coding!
