Do all Front-End jobs require TypeScript?

Question

typescript

Why introduce TypeScript as well? Almost all jobs in Front-End have TypeScript requirements, a good ~625 page book on this language (technical book).
Is the introduction to the work of this language worth it to learn this language well?

Answer 1

TS makes it easier to maintain the application (by making it very simple - it's easier to understand what data your function, object, etc. should return) and reduces the cost of development for the programming team. To get started, you can read: https://docs.microsoft.com/ru-ru/learn/paths/build...

Answer 2

First of all: autocomplete (when ide offers a couple of specific options to choose from, and not a list of 100500 supposedly suitable ones - this is a kaef), secondly: catching stupid errors at an early stage: you simply cannot call a function with an incorrect parameter, be it a typo or a logical error. This greatly speeds up and simplifies development.
Everything else, such as architecture, code purity, good practices blah blah blah - this is so, it may be - or it may not be.)
Well, you don’t have to study a thick book from and to. For starters, you can just write like in javascript, gradually learning new features and adding.
