Why Typescript ?

 

Why Typescript

 

Typescript is open source programming language developed and maintained by Microsoft. It is super-set of JavaScript and adds optional static typing to the language. Typescript is designed for development of large applications, which compiles to JavaScript. Can be executed on any browser.

 

Typescript supports OOPs features such as classes, interfaces, inheritance, generics etc.

 

Need of Typescript

There were many challenges faced by Microsoft while handling large scale enterprise applications. So, solution was to develop a language which is rich in features and can be transpiled to JavaScript. As our browsers only understand JavaScript. It can be compiled to JavaScript. That is why Typescript is called as Superset of JavaScript.

 

JS is client-side scripting language. We can do DOM manipulation, client-side validation, event handling etc.

 

But as the complexity of the code increases, it becomes difficult to maintain, because of the limitation of the JS. But JS is the only client-side scripting language and browsers only understand JS.

 

JavaScript Limitation

JavaScript is dynamically typed. It means deciding the data type of variable at runtime.

JavaScript doesn’t support OOPs fundamentals.

                Nilkanth dham swaminarayan Temple, Poicha Gujarat Location:     Temple is located in Poicha village on the bank of river Narmada. I was in Vadodara and planned to visit a Nilkanthham with my brother. So Poicha is approx 70 kms from Vadodara. One of the best thing I loved about Gujarat was their highways road, Its a delight to a person who loves driving and also to who doesn't, and that's the reason they have high cost tolls. One can easily reach to Poicha through google map navigation as there were not too many turns on way. Parking and entry fees: We gave rupees 30 for car parking, if you have bike you only have to pay rupees 20. Parking area is huge.
