tennien | 8 years ago | on: 10 Interview Questions Every JavaScript Developer Should Know

Classical inheritance is rarely "an appropriate choice" but prototypal inheritance is appropriate "any time you need inheritance"? Classical inheritance is syntactic sugar for prototypal inheritance.

Most users don't think Py = Python. Most associate it with the number. See name discussion below.

We're glad you like us!

- Definitely wanted to keep this option; no reason to force it on everyone.

- We let you learn at the right level.

- Believe it or not, we cover the core language. So once you finish JavaScript, you'll know enough to build a project or pass an interview at a top tech company.

- Completely custom; the design idiom is a common one.

- We're about to add this!

- If you want this, check out our coding interviews course.

- You're welcome :)

You'd be surprised! The coding interview questions are real-world questions used at real tech companies. Once you can answer them right, you can get a job.

I'm literally typing fixes right now. We'll get this out ASAP.

We actually do have an android version in alpha: https://play.google.com/store/apps/details?id=com.py

We changed our domain from py-app.com to downloadpy.com a couple days ago, so if you don't see us first this is probably why. Our old domain ranked consistently first.

Keep in mind many of our users don't even know python. We answer about 200+ questions every day in our in-app chat, and we've yet to hear someone get confused.

Right now we're planning on doing one thing really well before we do more. But there's no reason this model doesn't work for other subjects.

Great you love it! We're building more Swift content right now! Commutes are a perfect use case.

Right now we're focusing on our best programming courses. We're about to release courses like Data Science and Machine Learning. Apologies about the screenshot: it's out of date and Apple won't let us update it without submitting a new version.

Great question! The code is kept short, the output appears below the code, and we deal with typing by using a customized keyboard and letting you type in whole function names with a single tap. It's hard to explain without showing you the app :) Check it out.

Anyone is always allowed to use our app! We've found it very effective in leveling up engineering skills as well as taking people from 0 to coder.

Few of our competitors are mobile focused. Most people don't have hours to sit in front of a computer, but waste a lot of time commuting, standing in line, etc. Py is designed to utilize this time.

Great question about UX. It's hard to type on a phone, so we use a customized keyboard and group things into reusable elements.
