How are sprites enlarged?

Question

Canvas

So I noticed that in some unity tutorials they take a 32x32 sprite and increase it without losing quality. How can this be done on js canvas?

Answer 1

Everything is a little different in js/canvas.
The required sprite map is taken for the given segmented canvas resolution by the event of its resize.
Logic - as in adaptive layout, where the necessary styles are specified in css through @media.
