I have found that Typescript really shines when you're are working in a group of developers. No one can "tack on" random object properties that other developers don't know about. Also, you can define your interfaces or abstract classes and other developers can work completely independently from each other using those definitions. I totally agree with not trying to insert it into an existing project. There are a lot more design concepts that become available to you with Typescript that just don't exist with JavaScript. Trying to insert it basically forces you into just hacking types into your JS constructs where the design could be better with the other features.

But in most cases - when you learn TS, you won't touch JavaScript, like... at all. TypeScript eliminates like 90% of problems you would have while using JS like invalid type usage; hesitation, which type is a certain piece of code or making "stupid" mistakes like "accidentally adds number and object instead of two numbers". I hope more TS stuff will appear on this channel.

Which is faster -- writing code quickly and then debugging it in runtime in JS, or -- writing slowly with TS, but have no bugs at runtime? Maybe my projects were small, but I don't feel the need to strongly type them. And also, reading the TS code is not that comfortable with all these :int and other additional syntax. I see that people coming from strongly typed languages love TS. On the other hand, people coming from loosely-typed languages HATE TS.

@almogosheriko

2 жыл бұрын

This highly depends on how big your project is and how many different parts it has. The more parts, the more time you'll spend bug hunting and runtime debugging in JS compared to TS. Sometimes those kind of bugs can't even be found until a customer reports them in production, which costs a lot more money to the company when it happens. You don't have to add :int syntax most of time. Most of the variables are inferred from the initial values assigned to them. For instance, typing 'const myNum = 5' will infer it as type number.

Kyle as always great video, short and very descriptive. Been a fan of yours for a time. Could you start a small typescript series like the intermediate stuff like declaration files and so.

Great video! For me I think people have sold the idea of Typescript completely wrong. Many times when I have asked why I should use Typescript the answer from other developers has been "because it is typed and types are good". I think this is wrong, because there is nothing you get by just adding types. As a JS-developer for many years you learn dynamic types and can read types with ease. Because you understand how the language is made up. You can even type-check in many ways with vanilla JS. Many times most of the bugs come from logic-bugs not type bugs. So when you say it adds types to many you are just saying you can get building errors for both logic and types. Where Typescript shines is by adding amazing intellisense through the IDE which almost writes my code for me. This for me is the reason why I am listening and want to know more about Typescript. Because this makes me more productive and gives me an actual advantage of Typescript. If you want to explain why Typescript is good explain the benefits you get by it compared to modern JS with transpiled Babel. Then again I think this video did a pretty good job of explaining the benefits.

Nicely said however I would add that if you want to add TS to an existing project to start with a new feature/service rather than trying to change everything at once. Also ask yourself which parts would benefit most, usually highly reusable things. For example build your component libraries and services in typescript and then the people consuming can use regular JS if they want to.

In my opinion it is always a more serious problem that people tend to abuse things (especially advanced and powerful things) instead of missing out stuff. TS is just the same as many of the other cool things, if used properly it can definitely help, but many people tend to overdo it like "Oh this is good shit, let me use it everywhere for everything, and whenever I can show off using more advanced techniques I would not use the stuff that everyone already knows." To me whoever does this in real world coding is just a junior regardless how many years experience he/she has. Interview may be the only exception though as that's where you are supposed show off a bit.

So essentially this is JavaScript that cannot run anywhere, which has to compile back to JavaScript that is essentially identical. And the gains from what I can tell is you get to enforce strict types. Yeah that's a no for me: got more important things to do like learning java, python, and c#. The only use I can imagine for ts is cross browser compatibility. If it can handle internet explorer then I think it might be worthwile. Btw people are not paying close enough attention to vanilla JS: which is taking leaps in improvements year by year. This will likely be another case of JS vs jQuery. Pretty sure JS will be including typescript features soon: if they aren't already available.
