We can consider Typescript as a Javascript language enhancer. It allows large complex systems to be built with this language without any hindrance and without it falling short of other back-end languages such as PHP or Java.
What are the advantages of using typescript?
One of TypeScript's biggest advantages is that it makes it possible for IDEs to provide a more secure environment by pointing out errors as code is typed by the user. The TypeScript language adds static typing to JavaScript, which originally had dynamic typing.
