typescript vs javascript

1JavaScript:
2function my_function(my_param) {
3  console.log('do something');
4}
5TypeScript:
6function my_function(my_param: any) {
7  console.log('do something');
8}

1TypeScript adds strict typing to JavaScript.
2It helps to reduce the number of errors in your code.

4Apart from strict typing, TypeScript introduces
5a plethora of features like Interfaces, Mixin classes, Enums
6and much more, as discussed later in the article.

1// What differs typescript from javascript is the strict usage of types.
2// Javascript is a loosely typed language, 
3// while Typescript is strictly typed.

5// Javascript
6let car = 'BMW';
7let age = 15;
8
9// Typescript
10let car: string = 'BMW';
11let age: number = 15;

1They are really almost the same theres not the same param types like
2JAVASCRIPT is function myFunction(param)
3while typescript is
4function myFunction(the_param: something)
