Why don't the keys work? JavaScript

Question

When I ran this on browser while making the game the player would move around normally wthout a problem, after copy pasting the code in SoloLearn it wouldn't work however: https://code.sololearn.com/Wa1603A8A0a1

Answer 1

Add tabindex="0" as attribute to the canvas tag.
Add canvas.focus() to your script.
And finally add preventDefault() method to the keyDown and keyUp event handlers.

Answer 2

Karak10,

Error Line 10-11

Was having minor syntax error

canvas.width = window.innerWidthl
canvas.height = window.innerHeight;

It should be as

canvas.width = window.innerWidth;
canvas.height = window.innerHeight;

It's works fine with this change.

Any way I don't know how to play game this fix will keep it working.
