Flashcards 2.0

If you are learning to code, it is often hard to discover and memorize all of the functions of a programming language. STJ: JavaScript Flashcards make it super easy. They combine stateoftheart memory techniques with a fun-to-play card game to help you remember functions faster.

Here is the science behind STJ: JavaScript

According to research, images help commit information to our long-term memory, images transmit messages faster, images improve comprehension, images trigger emotions, and images motivate learners. In fact, 90 percent of the information transmitted to the brain is visual (source). That is why STJ: JavaScript’s intriguing and beautiful illustrations can help you to memorize JavaScript functions faster. Side-by-side with the fantasy setting and fun descriptions, STJ: JavaScript Flashcards are a great combination to help boost your memory! They are eye-catching and they create emotions – the cornerstone to memorize faster (source).

Dive into a fantasy world of Summon THE JSON, where excellent visual design, creatures, and fun descriptions will help you remember JavaScript functions as if by magic

STJ: JavaScript is an excellent choice if you:

- want to become a programmer

The Flashcards contain the most useful set of JavaScript functions that programmers use most of the time. STJ: JavaScript will give you a great overview of the tools every programmer has at hand. With that knowledge, it will be easier for you to start thinking about the best way to create your application from these building blocks.

- are invited to a coding job interview

A lot of companies use knowledge tests and whiteboard tasks to assess the knowledge of a candidate for a coding job. STJ: JavaScript helps you remember functions easier. Regular flashcards are boring and make it hard to connect programming functions with anything meaningful. On the contrary, STJ: JavaScript helps your brain store information about JavaScript functions in an efficient way. It increases the chance that your brain will give you all of the information you need during a job interview.

- are switching from another language to JavaScript

If you already are a software developer, then you know how confusing it is to switch to another language. Some functions are similar. Some are not. It is worse when you code in two or three languages at the same time. There are a lot of things to remember in every language. You need to find equivalents. STJ: JavaScript helps you progress faster in learning JavaScript. It shows you the toolset of the language and helps you remember it faster. Also, when you come back to JavaScript after a break, you can review the cards to recalibrate your brain faster.

- want to code faster without searching online

It is great that we have a lot of easily accessible sources on the Internet, we can find all of the information we need within seconds or minutes. But the Internet will never beat the speed of the human brain. If you remember function names, you can code faster. Moreover, your coding experience will become more fulfilling. You won’t worry about poor connection speeds or that the search engine does not find the answer you are looking for. You won’t be distracted by websites and online ads. Focus is one of the most important assets of a programmer. STJ: JavaScript helps you stay focused in the zone!

A word from the creator, Tom Smykowski

"- Hello, Tom. Why did you create STJ: JavaScript?"
- Tom: "I have eighteen years of experience as a JavaScript coder, as a programming educator, and as an employer. Everyday, I help young people to become developers. One of my biggest accomplishments in that area is being ranked in the TOP 3 percent of StackOverflow users for helping others. I run job interviews and code reviews. I often see young people struggle with getting a bigger picture of programming. Today, we have a lot of great learning resources. That is good, but this often leads to confusion and discouragement. So it became clear to me that we all need something like a compass, an essentials toolkit. That is what STJ: JavaScript is. These are the tools you have at hand. Learning programming is easier if you have guidance on how to start."

STJ: JavaScript is a card game

Summon The JSON: JavaScript is not only a Flashcard deck. It is also a game for everyone. Up to four people can play a game of STJ: JavaScript. The deck is divided into heroes, animals, and food. Some cards have points, some have superpowers. You can combine them to win battles against other players.

A game of STJ: JavaScript can be played by anyone. You don’t need to have any prior programming knowledge to do so. In fact, it is a great way to spend time in a mixed group of geeks and nongeeks. You can play it with your family, your friends, and your colleagues. Even when meeting new people, a game of STJ: JavaScript is a great ice-breaker, a conversation starter, and a way to spend time with other people, chat, and bond. Have a great time together!

Great quality!

I really liked how unique this game is for studying. I’m very new to JavaScript so all of the terms seem foreign to me but I’m already learning. Great product


Learned A Lot!

I have been learning JavaScript for about 8 months now and this deck has truly helped me to remember some of the best methods JS offers. This product definitely improved my learning speed and I bought this deck when I was 5 months into learning JS.


Great for JavaScript beginners!

I am new to JavaScript and needed to find a more creative way to help me learn JavaScript. The quality of the cards exceeded my expectations. The cards have proven useful, you can play them as one player and saved me from having to make my own flashcards.


Engaging and awesome

I absolutely love these cards and look at them multiple times a day. The fantasy pictures really do make a difference in having fun and learning. I love that there are multiple games games for a single person, two and up to for players


Hilarious. Bought this for a meeting with a few friends at my house

Hilarious. Bought this for a meeting with a few friends at my house. It was awesome! We're all excited about playing again. It's also easy enough as far as the game play goes that I think just about anyone could get the hang of it right off and have a good time playing. It's simple to play!
