Write it both ways

2021/02/02

Hello friends, so today I'm driving so that's the background noise you're hearing but I wanted to talk about how I make a decision about which direction to go when I'm talking about like writing code in multiple ways so like when the writing code there's like infinite ways to do things and you really can just slice this in any direction that you choose and lots of those decisions are pretty arbitrary and,Yeah just like it's not so cut and dry it's subjective and so the best method that I've found

Hey friends so today I wanted to talk about how important it is to communicate and in particular I want to highlight the importance of communicating what you and your team have done to your higher-ups. So anytime that you or your member of your team does something spectacular you should send an email to your boss or to your teammates bought. So there's nothing wrong with saying hey boss, I did this thing and it was really difficult and I really glad that it worked out and I just wanted to let you

How to test Redux

3 Minutes with Kent ·

2021/01/30

Hello everyone. So today I want to talk about testing redux. So I know that I don't really use redox like a lot of people know that I am not a huge fan of redux any redex project. I worked in would just became very difficult to work in. But I know that a lot of people are using redux and especially if you are probably using redux tool kit, which is great. So anyway, as far as testing redex goes. You shouldn't actually ever be testing redex. You pretty much always want to test the components that

TypeScript: Don't type array method callbacks

Hello friends, this is a little bit later than usual but I just wanted to get this in because I want to do this every weekday. So today I want to talk about TypeScript and in particular map. So I wrote a blog post recently that talked about converting typescript or fetch a fetch implemented or calling fetch in a function over to TypeScript because when you call fetch the return value from the dot JSON on that response is going to be any and so you have to explicitly. Give that a type annotation. And

Where do unit tests fit?

3 Minutes with Kent ·

2021/01/28

Today I was in a piano discussion for test JS Summit and a question was asked about like what's the use case for unit tests if we focus on integration and component level tests. And I talked about this and and it was kind of more about like what what's the shape of our testing trophy or testing pyramid or whatever like where do we focus our tests? And I talk about how I recommend that you focus on integration and component-type tests and try to mock as little as possible. I typically don't mock

Creating Content: My Secret to Learning

2021/01/27

Hey there friends So none of you are content creators none of you aspire to that or anything but I kind of want to change your mind on that a little bit. Creating content isn't just for the people who are out there creating content and getting paid for it like me or whatever I didn't start getting paid with the concept that I create and much the content. I create is actually not paid. My but like I often actually get asked about like, how do you learn stuff and and how do you like know the stuff

https://github.com/kentcdodds/rename-gh-to-main Hello there friends. So today I'm going to talk about what I did yesterday and that is I spent just like an hour to renaming all of the default branches on my GitHub repos from Master to Maine. Now, I'm not going to really explain directly why I actually have a article that you can go read but Git and and GitHub are moving the default branch from master to main fork historical reasons and you know references to slavery and that sort of thing. And so I

How to approach writing tests

3 Minutes with Kent ·

2021/01/25

Hey there friends. So today I'm going to talk about testing and the users of your code and how you should think about like how what do I test? So pretty common question. And the answer is basically you take a unit of code that you want to have tested that could be a single function or it could be an entire application. It really just comes down to what you want to get confidence in. Most of us are probably in the camp of like I just want my to be sure that my entire application works and that's

Don't Side-step TypeScript

3 Minutes with Kent ·

2021/01/23

Hello everyone So today I'm going to talk about TypeScript and tricking type script versus fixing your code So, you know, the the null non-null assertion thing where you put the exclamation point at the end of something to say, hey type script this isn't going to be no or whatever. I don't really use that. There's actually two reasons. One of them is because it looks like when you're looking at the code that looks like that's a feature of JavaScript, but it's not and so I don't really like using

Concerning Libraries and Frameworks: Build or Install

3 Minutes with Kent ·

2021/01/21

Hi there so today I wanted to talk about the merits of a framework I get this question quite often like when do I decide to bring in a framework or even just bringing in libraries versus just build it yourself. And so first on like the framework side of things if you're building something that's like basically a HTML page or you're doing some surveyor server template thing and you just need to enhance your app a little bit with some JavaScript so therefore it's more of a website than an app. Then

2021/01/20

Hey folks so I guess I need to do this because people keep on bringing it up and so I'm just gonna mention it. If you aren't aware a month or two ago, I unfollowed everybody on Twitter and now I follow zero people on Twitter and I changed to lists and so the reason that I mentioned this is because a lot of people see this as some sort of power move or some nefarious purpose. I've done this. I don't know. I don't understand why people have yeah and I know that not everybody has but several people

Hi there friends So today, I wanted to talk about understanding the syntax of JavaScript. Now, I most of us when we're learning JavaScript, we are introduced to each part of syntax and some of its capabilities and we just kind of learn about that syntax through experience of working with it and there's nothing wrong with that approach that's pretty like the the best way to learn anything is really just practical application. But there are often things that you skip over when you just focus

Hey there friends. So today I wanted to talk about TypeScript again, and I want to talk about adopting TypeScript. So when I first started into TypeScript I was working. I I'd been doing flow for a long time and then I switched over to TypeScript. This is at PayPal. And one of the first projects that I used TypeScript in was this project called PP React, which is short for PayPal React. It was a component library. And I I was working with a lot of abstractions as my first and my first foray.Into

Real World Debounce

2021/01/15

Hey there friends I've been making notes of different things that I do or like see in the real world that is like a good analogy for programming concepts and one that I thought about recently was the programming programming concept of a deep bounce and scanners at the grocery store. So, I don't know about you but I I haven't used an actual like person skinning in my groceries for years. I use the self checkout now. I like that a lot better and even though maybe it's not as fast. I don't know. I just

Hey folks I was just thinking about something that yeah, I get questions about how do I break into the content creation world and stuff like that pretty regularly and something just occurred to me that I thought was kind of interesting and that is that I occasionally will see people with a handful of followers on Twitter and and like no sense of a newsletter of any kind or anything publishing books and making courses, you know, paid courses and things like that. And I think that I mean, I'm I'm not

Hey there friends. So today I wanted to talk about something that was just on my mind yesterday. I was meeting with one of my learning clubs friends who were going through Epic React.dev and it was just so fun to talk with them and things and they asked me about how I'm productive and and get a lot of things done. And I mentioned that I I pretty much like over the last several years have just made sure that everything that I do is has a I increase the value of the impact and I've got a blog
