Good resource for learning JavaScript and better than Codecademy

This game is simply amazing. Better interactive tutorial for beginner than Codecademy.
allenleein on HNGreat resource for learning Javascript. Good work!

Nice idea and well executed

It's a nice idea and really well executed but the second test just demonstrates to me how JS is not an ideal language for a beginner to learn as you're thrown straight into async…

Objections
Learning curve too steep for beginners, especially level two
From 3 comments
It's an interesting game, but I was immediately put off by level two, which sinks you into the limitations of the robot API by making you introduce a counter that needs checking.…
Confiks on HNOn the right track, but waaaay to steep a learning curve for an absolute beginner, assuming that is the target audience. In-line incrementation and Mod operations on level 2 is a…

Code is lost when restarting a level or the page
From 2 comments
A neat concept but frustrating when restarting the page loses any code in the script window.
ahmeni on HN:/ Fun idea, but I wrote a chunk of code for the third level, bumped the electro thing, died, clicked the restart button and it wiped my script. I should know better than to…

Only one action per loop tick; later calls overwrite earlier ones
From 3 comments
I don't understand. Are you referring to Level 2? What's going on there is just that the robot can only enqueue a single action for the tick. So calling multiple actions will…
always_good on HNI think it's just a case of leaky abstraction. I'd change the API to something like: ``` robot.action = { action: 'jump' }; robot.action = { action: 'move', amount: 4 }; etc. ```…
kaoD on HNAnother idea is to return a map of actions. ``` { jump: true, move: 4, shoot: true } ``` Making the user increment a nonce and use the remainder operator just to do multiple…

Show variable state during execution via a debug view
From 1 comment
Or the action could be the return value. IMHO, trying to guess the physical model by experimentation is painful. Why not propose a debug button to display the state of variables…

Questions
Whether multiple actions per loop are intended behaviour
From 3 comments
That's not right. You can put more than one action in the loop. This slowly completes the level: ``` function loop(robot){ // your code here robot.move(1) robot.jump() } ```
IanCal on HNIt shouldn't according to its own instructions. I bet jump() has something like `if (robot.touchingFloor) { action = 'jump'; }` which makes your code work because it doesn't…
kaoD on HNAh I stand corrected, thanks. So I guess it's performing the last valid action.

If I remember correctly, Google's Blockly Games used to allow JavaScript on more than just the last "level". It definitely starts at a much earlier point in the learning process.…
