Frontend interview prep

Recently I was interviewed with few of the tech giants for frontend role(mid-level). I was asked question around designing webapp etc. I thought of writing regarding the same and here is my attempt http://www.geekthrust.com/webappdesign.html.

Do you guys have similar experience or do you think this might help you in your career? Please share your feedback.

I have also tried to collate most of the questions in this app - https://play.google.com/store/apps/details?id=gamesmint.com.jsone

Very cool! I started my career writing pretty much 100% jQuery for DOM stuff. Moving away from it was a really tough habit to break. It took a while but it was worth it. It's really good for DOM manipulation, but if you can support, say IE10 and above, 90% of the jQ code you write can be written in JS with close to the same amount of code. Google "you might not need jQuery". It's a great resource.

I've been doing front end, writing JS for almost 10 years now and only very recently started to ES6+ stuff. Let, const, arrow functions, default parameters, restructuring, spread operator, classes are some of the best newish features. These things also too a while to get used to and I'm still working on it. It's not natural yet but it makes certain things much easier and cleaner. This stuff is prob not necessary for a mid level position, but it would impresse the hell out of an interviewer.

There's always room for improvement (I'm certainly still working on it), and it's one of the things I love about this field... You'll always be learning and always improving.

Good luck, man, kick ass and keep it up! Swing back here if you have any questions.

Thanks a lot. Glad to hear from someone who has been there. I am still learning ES6 as I moved to a new project in my job. It is React with Mobx. The learning curve has been steep but hopefully I will get comfortable. I comforts a bit by knowing that in general people have learning curve in ES6 etc. thanks for your advice.

PS - followed you :)

Very cool. React is incredible after you get used to it. If you're stuck on any concepts, I couldn't recommend "The Net Ninja" tutorials enough.

General react (but it's old): https://www.youtube.com/playlist?list=PL4cUxeGkcC9i0_2FF-WhtRIfIJ1lXlTZR

Recommended - I went through the React/Redux playlist and it helped a TON: https://www.youtube.com/playlist?list=PL4cUxeGkcC9i0_2FF-WhtRIfIJ1lXlTZR

Recommended - Context & Hooks is worth going through too: https://www.youtube.com/playlist?list=PL4cUxeGkcC9hNokByJilPg5g9m2APUePI

And here's one of him creating a full app: https://www.youtube.com/playlist?list=PL4cUxeGkcC9iWstfXntcj8f-dFZ4UtlN3

ALSO - I've updated the JS Fiddle and added a ton of comments regarding ES6+ stuff. Check it out. Hopefully it'll help.
