JavaScript Which is more efficient JavaScript array search or MySQL LIKE query? [closed] what more efficient ac or dc,what's more

Answer:1

This is just speculation, but without testing, immediately I'd go for the MySQL query. MySQL has been optimised by its developers for the best search/sort algorithms - that's its job (one look at their benchmark manual will give you an idea as to just how much they care). The people who write the JavaScript interpreters won't have had as much time to devote to optimising their search/sort algorithms.

As an added plus, the Javascript option is dependent on the client's computer speed and browser - a slow device with a poorly implemented interpreted will take a much longer time. However, the MySQL option depends on your server, and therefore is completely under your control.

Some tests

JavaScript array with 10,000 values, comparing against a set value (jsfiddle.net/c6rpK/) - I get approximately 12ms

For the same test using MySQL I get 2.3ms
