And I think node uses one that optimizes string concatenation, possibly making that the fastest way to do it. emodendroket 11 years ago Yeah, as far as I know in modern JS engines += is actually faster than using an array. x1024 11 years ago [citation needed]It's really nice how we once again depend on "I think some guys do it like this" for performance. What happened to standards?What's next? SEO for code?
