JavaScript & SQL Reviews

JAvA/script application.

Imthuteepot on

United States

This may strike you as somewhat odd and/or much like probably nothing important.. but this app. Is a really really complicated. I am a small town country girl and I know that you.., whoever you are.. or aren’t.. for that matter of factually ..,, anyway I would have to be an idiot to not believe in things that I couldn’t see because I’m not there yet , and would appreciate knowing this knowledge as well. Everything is up for grabs tonight today tommorow just be careful what you type. An inspiration and an idea to keep up the good work. Man.

Missing ECMAScript Features

HardRockJon on

United States

Although interfaces are listed in the table of contents. There actually isn’t any information on them. Instead you get “ //In Javascript there are no interfaces //ECMAScript 6 feature” and then classes examples. The correct way to do this is show interfaces with a note they aren’t a JavaScript feature.

A lot of cool information on here. Helpful to learn.

Love this

Was just thinking of something like this in the shower. Glad you made it. I also agree with the person who suggested a little walkthrough, possibly with comments of what the code does or when to use it. For example, what’s the difference between linear search and fast linear search? I would assume fast linear search should always be used because it’s “fast” :) Thanks for the app!

Thank you

Very useful, thank you

Great Resource

Just getting started so far, and I love it. Thank you!! I love the way it is structured, helps organize the language and the practice for me.

Great app: could be even better with descriptions

I’ve been looking for a programming resource like this for a long time and just stumbled across it in the App Store. It has not only met my expectations but I have also learned new concepts. The problem with learning new concepts is that you don’t always know if you are interpreting the code correctly. The one thing that would make this app over the top is including descriptions of what is going on in the more complex topics of the app, such as the Algorithms section or the Multi-Thread section. Each of these sections would benefit from a deeper dive into the concepts behind their formation. I would pay $9.99 instead of $1.99 for a resource with useful descriptions like this. Thanks for developing this app!

Good app.

One thing it would help people who are still new to programing if keywords like “loop” and “Boolean” had a small definition section of what it does like “Looping is a code in a program that repeats automatically”

Useful for reminders and memorization

I primarily wanted an App that can teach me techniques and tricks in JS. I ended up finding this goldmine of an App. I recommend this to any developer learning JS if they want to sharpen their JS skills.
