There are many large open-source projects that have decided to retire TypeScript since September 2023, and many people who are actually studying it are quite worried.

I was curious about this, so I took a look around.

First, I need to explain TypeScript to those who don't know it, and then go over its history.

1. JavaScript vs TypeScript

People who started with vanilla JavaScript, like me, and moved on to JavaScript, such as jQuery and React, have a negative impression of TypeScript.

There are things that I don't want to learn anymore, but there is a certain freedom that comes with just JavaScript.

Some people say that it is a language without roots? Or that it's not a language because it's a script.

All languages have an important step called building, but JavaScript doesn't build because it's a script.

If you have built it, it's actually similar to something added in various frameworks.

Therefore, error detection, etc. does not work at all. The limitation of scripts is that if it doesn't work, it spits out an error.

(That's what a script means.)

But it's like a street kid, it's just rolling around, but it's kind of charming.

2. Is TypeScript widely used?

If you look at the 2023 programming language rankings, it is the 5th most used language.

It is well received by web developers.

That's why the TypeScript retirement issue seems shocking.
