Drawing smth from an array

[south quartz]

Lets say that I have an array just like this:

[
1, 0, 0
1, 1, 0
1, 1, 1
1, 1,0
]

I wanna convert this to a drawing (each value in the array being 1x1 pixel) using the HTML/JS canvas api. I couldn't figure it out myself and I don't really know which technical term it correlates to thus I couldn't Google it myself.
