Array.from({length: 6}, (_, i) => i)

Not so many, but for example when working with flat matrices,
`[0,0,255,1].repeat(len)` for generating quickly a uniform imageData
But even with one item, I find `[x].repeat(n)` more explicit than the 2
other alternatiives
It's somewhat close to array comprehensions (that I don't really miss
though)
