RxJS is definitely a very powerful tool. But in my every day usages of async related things, I've never felt that I need to use something as powerful as RxJS to do it (instead opting to use something like async/await, promises, etc). Other than very specific use cases like making drag and drop ridiculously easy, RxJS really just felt like it was just killing a fly with a bazooka.

Do you have other examples of when you would prefer to use RxJS instead of other async related libraries?

Yeah well honestly with RxJS the benefit is that you are moving your business logic into a domain specific language - so it's much easier to copy/paste code into new frameworks and libraries without large rewrites. You're also essentially future proofing your code two ways. The first is - RxJS provides an abstraction in the form of Observable for you so that you can easily change out the inputs at a later time. The second is - later on, it's much easier to add on functionality by just adding on another operator or chaining together a set of things, again, without having to rewrite your code much.

I'd say it's super smart to kill all the flies with a bazooka because later on you may be thankful you have that abstraction in place.

Also it's just more declarative and easier to read.

I always use RxJS so I don't have other recs on other libraries! :)

One of the selling points of React is to just write JS, no need to decipher a DSL. Why doesn’t RxJS take this approach?

Depends what your working on. When I worked in FinTech you have a large stream of events coming down the pipe. Something like Rx works very well for this.

Yes! For things like backpressure, multi plex web sockets, exponential backoff, cancellation - all these are great use cases for RxJS.

Hey Tracy! Awesome to see you doing this AMA, despite you stealing Jay from us :P

A few questions:
What was the GDE process like? Did you reach out, or did they? Has it helped you in your career?

What do you think is the largest barrier for newcomers to RxJS? How can the community help out?

Collapse

Tracy Lee | ladyleet Ask Me Anything

The GDE process is different for everyone! They reached out and told me to apply. You can also be recommended by another GDE. I believe you can just apply as well but the rules change so often that I'm not confident if you can just apply these days. I think the benefit of being a GDE is being able to have access to new Google technologies! Being a GDE is just about doing what you already do and helping promote Google Technologies through community involvement.

Largest barriers for newcomers to RxJS would probably be knowing how on earth to do anything. We currently have the RxJS docs initiative and the new docs are hosted at rxjsdocs.com. These are beta but pretty easy to contribute to. I think also finding the time to take an hour out and pair with someone on Rx related things is always really nice and helpful too! :)

What's the process of applying for GDE? And is it a status you need to re-up on or do anything to keep?

Thread Thread
 
ladyleet profile image
Tracy Lee | ladyleet Ask Me Anything

Well, I think for right now you have to be recommended by another GDE! Typically you become a GDE because you are already in the community and people already assume you are a GDE. That has been the case for myself and many others. :) I'm not sure if you ever "lose" your GDE status - but definitely the program expects you to track what you do as a GDE and those metrics are reported on. :)

Hey Tracy! What do you feel is missing from web development today? Missing Web Platform features, libraries or tools?

Collapse
 
ladyleet profile image
Tracy Lee | ladyleet Ask Me Anything

Well ya know... I would say that a Chrome Contributor Days is definitely missing from web development today! πŸ˜‰

But all in all wouldn't it be great to have a playground where developers can go and play around with new technologies? Or somehow make it easier to find information? A lot of what I hear in web development is that people don't know what they should learn and would like to be prescribed more the most important things. So I think that visibility into that is important.

I also think that adoption of certain APIs, let's say, would be cool because that would help surface some of the items that are necessary and important for web developers to take note of.

Can you explain RXJS like I'm five?

Tracy Lee | ladyleet Ask Me Anything

Hahaha :) Observables are just functions in JS - they don't do anything until you subscribe to them, or call them. It's not that hard so if you're learning promises currently I say why not just learn RxJS bc it's basically the same thing but with more benefits? :) But, everyone has their own opinion! :)

Tracy Lee | ladyleet Ask Me Anything

It's definitely fun! Definitely not as intimidating as it may seem. Working with people you really enjoy working with and doing projects that you find passion in is the best. I became a core team member because I put in effort into the community and at some point in time, that was recognized. :) And that was nice. :)

Hey Tracy! πŸ‘‹

Wanted to ask: How do you find the time to do SO MUCH community work, even though it's a part of your job?

You've done a tremendous job of connecting individuals who are from distinct parts of the community and weaving a fabric of awesomeness. I've seen others attempt and fail to do the same, so I'm curious about your thoughts on how to bring people together to discuss common goals and their differences.

Collapse

Tracy Lee | ladyleet Ask Me Anything

I think I've just been good at doing this my entire life. Finding connections in people and suggesting things and just overall having the power of suggestion. :)

I also make sure to always follow up with the people I want to follow up on and make an impact. Those of us who are blessed with the ability to make connections and change the world, always should. You are one of those people too! <3

I was also lucky enough to make this a part of my "job" essentially, and that makes me so happy. Helping people just makes me happy. :P

Plus, I think I try to encourage niceness and am not afraid to call people out on their silly BS sometimes. ;)

Hello Tracy, thanks so much for taking the time to talk to us! ❀️ I'm super curious about how you got into programming (in general) and web development specifically - did one or the other draw you in first? I've only played around with RxJS a little bit, but I really enjoyed the pattern and the documentation. What made you decide to become a core team member?

I'm also interested in how you manage so many things! Is there anything you do to recharge/specific ways you like to stay organized?

Tracy Lee | ladyleet Ask Me Anything

Hi Anna! I just picked up the computer and learned HTML/CSS/JS one month and kept going! The community is what kept me going - being constantly surrounded by people who were awesome and as passionate. MENTORS as well - if I didn't have mentors around me I'd just sit there for hours at at time stuck. My mentors even now help me get unstuck and when they do I realize that I was only 1% away from a solution. When I do it by myself, I feel like I am 80% away from the solution.

RxJS core team - they were all friends and they needed a little bit of help with organization, the docs, and just some new energy so I was just there, helping out, and then a few months later, I became officially part of the RxJS core team!

I use evernote to stay organized. Religiously! I also have a very intense calendar. I plan out my year in Nov/Dec so I can very much tell you where I'll be in December. :)

And by plan everything out - I mean I plan out all my monthly social activities and put it on my calendar, as well as events, conferences, and where I'll be physically in the world! My calendar is usually booked out a month in advance.

I also make sure I have time for myself to code in that time. :) I meditate to stay recharged, cook, and go on walks. But sometimes I also just sit in bed and complain to my BFF @benlesh (jk but not really).

I do a bunch of conference speaking myself, but I've only done 1 keynote so I'd love to pick your brain a little on how you do yours: What's your process look like for developing a keynote talk?

  • Do you generally reach out to a conference, or do they come to you?
  • How do you pick the best topic for you to speak on for a given conference?
  • How do you research the conference and audience to figure out what parts of your knowledge will be useful to them, vs what they might already know or what might go over their heads?
  • How can you tell when a project or product is "good enough" to give a talk about?
  • Got any favorite heuristics for balancing time spent on speaking with time spent on doing stuff to speak about? I kind of struggle with this personally :)
Collapse
 
ladyleet profile image
Tracy Lee | ladyleet Ask Me Anything

Hi E! :)

I usually work on my keynote talks with the organizers but make sure it's a big enough idea that is relevant to the entire conference.

I used to reach out to conferences but now they just reach out to me.

I choose my topics based on what I'm excited about - the only way to choose talks.

Well... I go to very targeted confs so I usually apply what I'm talking about to the actual technology.

If I find a product or project amazing, then I'll talk about it! :)

I try to spend about 20-30% of my time on learning new tech or working on talks and speaking. I just block it off bc it's important to me - though I should do this with working out too dangit !:)

Thanks for doing this AMA. For seemingly everyday there is a new framework or library. What kind of path would you recommend for someone wanting to be in the javascript arena, ie, learn JS first then move on and if so, how much JS should you learn before continuing onto frameworks. Thanks.

Collapse
 
ladyleet profile image
Tracy Lee | ladyleet Ask Me Anything

I mean honestly I'd poke around at all of them and ask questions on twitter and around your entire life. See who will be your mentors or willing to help, what is the easiest or most comfortable, or what you get most excited about, and go from there.

Some people say only learn vanilla JS. That's a great idea but I will also say it's not that bad to just learn a framework and JS along the way. The most gratifying and satisfying way to learn something new, at least for me, is to see immediate results. That is why using Ember-CLI after 2 weeks of JS was the best way for me to get stoked on staying on the JS path.

I literally would say just get on a framework while learning JS. It does not hurt.

What advice would you give a software developer who is thinking of starting their own business (high growth startup or otherwise)?

Collapse
 
ladyleet profile image
Tracy Lee | ladyleet Ask Me Anything

I've started quite a few companies myself so... I would probably say know who you are getting into business with or know what value they are bringing to the table and make it very clear. Always have a 1 year cliff for all founders when starting - a lot can happen in a year. I would also say make sure to get a good lawyer and the paperwork done properly because then it's way easier to get cofounders and investors interested and involved. Until then there is nothing for them to do bc you're not ready.

Also, do NOT quit your job. If you can't work full time and do your startup and gain traction, you won't be able to full time. I don't care what you say bc you are also not driven enough if you can't handle both at the same time and gain some sort of traction. Once you have found product market fit or revenue or funding then quit your job.

What has your experience with fundraising been? Do you recommend accelerator programs?

Thread Thread
 
ladyleet profile image
Tracy Lee | ladyleet Ask Me Anything

I think accelerator programs are great potentially for the network or for money or for structure. It depends on how structured you need things. These accelerators will give you foundation. For me personally, I'm already pretty structured so I might consider accelerators and excel, but I am also able to do it myself and be successful since I've gone through the path. Some people also can't afford the time for accelerators and can only work nights and weekends which is how I started my first company.

Fundraising! Fundraising is a TON of fun once you gain traction. Your first investors will probably just be your advisors. And honestly, my first "real" investor was just a guy who went to a Dishcrawl (food event, my first company) with his wife, realized I did startup stuff. We got together because I just wanted to soft pitch him. When we chatted he fell in love with the idea, saw that I was coachable, and helped guide me.

One thing is - you are always in charge of your own destiny so don't "rely" on someone else or some investor or lawyer to make connections for you, etc.

Also, just be around startup stuff so you have more serendipitous encounters and ideas.

TALK about your idea ALL THE TIME. I hate it when people are so scared someone will steal their idea. Your idea is not that great, and your execution is zero. So... literally... just talk about it so you can improve it and so others can help you improve it.

The key is understanding the process and figuring out how to scale those relationships in a way that does not kill your team! :) Sometimes it also requires a lot of patience because it can be slow.

Wow, you've made so many neat things I hardly know where to begin! Since you say to ask you "anything", the first question to cross my mind is about one of the hardest problems in computer science: What're your thoughts on and techniques for naming things, especially businesses and projects? Got any favorite stories about how picking the right name and scope for a project helped it out down the line?

Hhahaah.

Well, one of my first products was a gift app. And we could NOT for the life of us agree on what to name it.

Me and my cofounder at the time were eating in Mountain View at a restaurant called Sushi Tomi. So we thought - Gift Tomi and named it Giftomi. We kept trying to call it Gift something. And then another person a few months later was like yeah you named it Gift to me! like Giftomi! And my mind was BLOWN.

Another one - I wanted to create an umbrella corporation and I was at an event explaining this to someone. He said yes, like an evil umbrella corporation. Then I thought, OMG EVIL is LIVE spelled backwards! So one of the names of one of my first companies was LiveUmbrella :)

hi Tracy!. First off, thank you so much for doing this Ask me Anything!

A very important question.

Tracy Lee | ladyleet Ask Me Anything

Honestly, just pick what you're passionate about. Learn what you want, and spend some time after hours to hone in on what you get excited about and become an expert. Then move on to the next project. I think the problem with JS is that it moves so fast and you always feel like you know nothing but the truth is that we all know something - it may just be in a different area of expertise than another. :)

Oh yes absolutely 100%! Plus once you learn JS or any other language, it's super easy to go back and forth and learn other languages. :) There is PLENTY of JS jobs and JS need these days. Node, for example, React Native for mobile, and just general front end too.
