+DrAzzy Yes, i have. The VDD pin sources only the current for the light, the VCC pin sources only the control circuit of the WS2812, which draws less current and at the 3.3 of Espruino therefore no Problem, because it's bypassed by capacitor. I go this way after magnifying the sample circuit on page 5 showing a series resistance of 150 ohms making it impossible to draw more then 33ma. I have tested it with 2 pieces on a breadboard and they are burning my eyes (at 255,255,255). This is just a test-setup, real projects get a seperate bypass-capacitor.
